Spin-lattice coupling and peculiarities of magnetic behavior of ferrimagnetic ludwigites (Mn_(0.5))~(2+)(Mn_(1.5))~(2+)Mn~(30+)B0_5 (M=Cu, Ni)

摘要

Temperature-field and orientational magnetization dependences of single crystals were measured. Both samples demonstrate significant field-depending temperature hysteresis and low-temperature counter field magnetization. The correlation of orientational dependences of these effects and magnetic anisotropy is analyzed; the role of spin-lattice interactions is discussed.
