This first introduction to the rapidly growing field of molecular magnetism is written with Masters and PhD students in mind, while postdocs and other newcomers will also find it an extremely useful guide. Adopting a clear didactic approach, the authors cover the fundamental concepts, providing many examples and give an overview of the most important techniques and key applications. Although the focus is one lanthanide ions, thus reflecting the current research in the field, the principles and the methods equally apply to other systems. The result is an excellent textbook from both a scientific and pedagogic point of view.

We report on simulations of BaFe 11 TiO 19 ’s magnetocaloric effect (MCE) at temperatures between about 4 and 250 K. The MCE in BaFe 11 TiO 19 unexpectedly displays two forms. Among 33 and 204 K, BaFe 11 TiO 19 shows an inverse MCE due to noncollinear ordering. But when the FM goes from 4 to 33 K or over 204 K, a direct MCE is employed. BaFe 11 TiO 19 ’s advantages may be useful in the hunt for magnetocaloric compounds that exhibit two or more successive magnetic phase changes. BaFe 11 TiO 19 is therefore a very promising magnet for cryogenic refrigeration, with potential uses in the liquefaction and storage of various gases.

A series of heterometallic carboxylate 1D polymers of the general formula [LnIIICd2(piv)7(H2O)2]n·nMeCN (LnIII = Sm (1), Eu (2), Tb (3), Dy (4), Ho (5), Er (6), Yb (7); piv = anion of trimethylacetic acid) was synthesized and structurally characterized. The use of CdII instead of ZnII under similar synthetic conditions resulted in the formation of 1D polymers, in contrast to molecular trinuclear complexes with LnIIIZn2 cores. All complexes 1-7 are isostructural. The luminescent emission and excitation spectra for 2-4 have been studied, the luminescence decay kinetics for 2 and 3 was measured. Magnetic properties of the complexes 3-5 and 7 have been studied; 4 and 7 exhibited the properties of field-induced single-molecule magnets in an applied external magnetic field. Magnetic properties of 4 and 7 were modelled using results of SA-CASSCF/SO-RASSI calculations and SINGLE_ANISO procedure. Based on the analysis of the magnetization relaxation and the results of ab initio calculations, it was found that relaxation in 4 predominantly occurred by the sum of the Raman and QTM mechanisms, and by the sum of the direct and Raman mechanisms in the case of 7.A series of heterometallic carboxylate 1D polymers of the general formula [LnIIICd2(piv)7(H2O)2]n·nMeCN (LnIII = Sm (1), Eu (2), Tb (3), Dy (4), Ho (5), Er (6), Yb (7); piv = anion of trimethylacetic acid) was synthesized and structurally characterized.

Near infrared (NIR) Y 2 Ti 2 O 7 :Ce 3+ /Cr 3+ /Nd 3+ phosphors were synthesized using a solid-state reaction technique. NIR luminescent performance of Y 2 Ti 2 O 7 :Cr 3+ /Nd 3+ phosphors was improved by doping with Ce 3+ ions. The emission intensity of Y 2 T 2 O 7 :Cr 3+ /Nd 3+ /Ce 3+ phosphors is significantly higher than that of Y 2 Ti 2 O 7 :Cr 3+ /Nd 3+ phosphors. The external quantum efficiency and internal quantum efficiency of Y 2 Ti 2 O 7 :0.5% Cr 3+ /0.7% Nd 3+ /1.5% Ce 3+ are 16 and 22.8%, respectively. The luminescent mechanisms of the Y 2 Ti 2 O 7 :Cr 3+ /Nd 3+ and Y 2 T 2 O 7 :Cr 3+ /Nd 3+ /Ce 3+ phosphors were investigated. As a result, the effective energy transfer process from Cr 3+ to Nd 3+ ions exists in Y 2 Ti 2 O 7 :Cr 3+ /Nd 3+ phosphors, while the effective energy transfer process from Ce 3+ to Cr 3+ and Nd 3+ ions exists in Y 2 T 2 O 7 :Cr 3+ /Nd 3+ /Ce 3+ phosphors. NIR emission intensities of LED devices assembled with Y 2 Ti 2 O 7 :0.5% Cr 3+ /0.7% Nd 3+ /1.5% Ce 3+ phosphors are better than those of LED devices assembled with Y 2 Ti 2 O 7 :0.5% Cr 3+ /0.7% Nd 3+ phosphors at different work currents. In addition, the temperature-sensitive behavior of Y 2 Ti 2 O 7 :Cr 3+ /Nd 3+ phosphors was also studied. Their LIR and S a values monotonically increase in the temperature range of 303–393 K. The maximum S a values of Y 2 Ti 2 O 7 :0.5% Cr 3+ /0.5% Nd 3+ , Y 2 Ti 2 O 7 :0.5% Cr 3+ /0.7% Nd 3+ , Y 2 Ti 2 O 7 :0.5% Cr 3+ /1.0% Nd 3+ , Y 2 Ti 2 O 7 :0.5% Cr 3+ /2.0% Nd 3+ samples are 0.79 × 10 –2 , 0.88 × 10 –2 , 1.24 × 10 –4 , and 2.53 × 10 –3 K –1 , respectively.

A phenomenological model (PM) is employed to simulate magnetocaloric effect (MCE) of amorphous Fe 22.5 Co 22.5 Ni 22.5 Cr 22.5 Zr 10 (FCNCZ) alloy. MCE parameters are concluded via simulation at 9 T. The full-width at half-maximum, relative cooling power and refrigerant capacity are 209 K, 188.5 J/kg, and 138.7 J/kg, respectively, revealing the potential of applying the magnetic refrigeration over a remarkable temperature range, including cryogenic temperatures, which is practical in cooling devices.

—An experimental study has been carried out on the mineralization of oxalic acid H 2 C 2 O 4 and other oxidation-resistant organic compounds in aqueous solutions under the influence of oxygen, ozone, and ultraviolet radiation. It was found that in acidic solutions H 2 C 2 O 4 does not oxidize under the influence of ozone or UV irradiation in the presence of oxygen; when exposed simultaneously to O 3 + UV it has a low rate of oxidation. The possibility of photocatalysis of the mineralization process by Mn 2+ , MnO , Fe 3+ , Co 2+ , BrO , or IO ions was studied The most effective photocatalysts are Fe 3+ ions: in their presence and under UV irradiation, a fairly rapid oxidation of oxalic acid to CO 2 occurs, as under the influence of O 3 and O 2 . The conditions for maximum ozone conversion during photomineralization of oxalic acid have been found. The possibility of oxidative destruction of a more oxidation-resistant substrate, acetic acid, is shown during ozonation and UV irradiation of solutions with Fe(III) and H 2 C 2 O 4 additives.

This work presents a simulation of the magnetocaloric effect (MCE) for Mn-doped topological insulator Bi 2 Se 3 thin films using phenomenological model (PM). There is a good simulation of experimental magnetization for the Bi/Mn = 12.5 and Bi/Mn = 23.6 samples in low magnetic field along 〈1 00〉 direction. The MCE parameters for the Bi/Mn = 12.5 and Bi/Mn = 23.6 samples in low magnetic field shift along 〈1 00〉 direction has been determined. The high Mn content in Bi/Mn = 12.5 sample enhances MCE parameters more than Mn content lower sample. The MCE for Bi/Mn = 12.5 and Bi/Mn = 23.6 samples show practical use for cooling system in very low temperatures.
