Magnetic and magnetoelectric properties of Sm1-xLaxFe3(BO3)4 single crystals / E. V. Eremin [et al.] // Solid State Phenom. : Selected, peer reviewed papers. - 2015. - Vol. 233-234: Achievements in Magnetism. - P. 368-370, DOI 10.4028/www.scientific.net/SSP.233-234.368 . - ISSN 1662-9779. - ISSN 978-3-038

Аннотация: Sm1-xLaxFe3(BO3)4 (х = 0, 0.5, and 0.75) single crystals are grown by the flux method and their characteristics are investigated in the temperature range 5?300 K and magnetic fields of up to 9 T. It is established that substitution of nonmagnetic La3+ ions for magnetic Sm3+ ions increases the magnetization and weakens the magnetoelectric effect in Sm1-xLaxFe3(BO3)4. © (2015) Trans Tech Publications, Switzerland.

Ferromagnetic resonance linewidth in powders consisting of core–shell particles / L. A. Chekanova [et al.] // Bull. Russ. Acad. Sci. Phys. - 2017. - Vol. 81, Is. 3. - P. 351-353, DOI 10.3103/S1062873817030091. - Cited References: 4 . - ISSN 1062-8738

Аннотация: The dependence of the ferromagnetic resonance linewidth on the thickness of nonmagnetic shells in powders consisting of ferromagnetic core–nonferromagnetic shell composite particles is investigated. It is found that an increase in shell thickness reduces the ferromagnetic resonance linewidth by several times, down to values comparable to those for coatings with compositions similar to that of the particle’s core. The observed effect is assumed to result from suppression of the inhomogeneity of demagnetizing fields in a powder consisting of magnetic particles. © 2017, Allerton Press, Inc.

Аннотация: Heat capacity and intensive magnetocaloric effect (MCE) in manganites (La1-yEuy)(0.7)Pb0.3MnO3[y=0.2; 0.6] (LEPM) were investigated by means of adiabatic calorimeter. The heat capacity anomaly as well as the values of both the intensive (Delta T-AD) and the extensive (Delta S-MCE) MCE were found to decrease upon increased replacement of La with nonmagnetic Eu. However, because of widening of the MCE peaks, the LEPM compounds show the relative cooling power, RCP/Delta H, comparable to other solid solutions of manganites. Owing to strong effect of Eu -> La substitution on the Curie temperature, LEPM might have potential as the solid state refrigerants in multi-element cooling apparatus operating in a wide temperature range.
