PHYSICS AND MATHEMATICS
Spin transitions and possible nature of the long distant magnetic states
L. A. Boyarsky Novosibirsk State University
Abstract:
In organo-metallic compound Fe(t(DMPz)M)$_2$(ClO$_4$)$_2$ as the temperature decreases to 220 K takes place the spin transition from
high spin state to intermediate one. The susceptibilities of both phases obeys to Kurie-Weiss law, the high distance magnetic order not
observed.
In the system LaCo$_{1-x}$Rh$_x$O$_3$ the initial components LaCoO$_3$ and LaRhO$_3$ at the low temperatures are in the low spin, nonmagnetic states. Rhodium doping at x> 0.04 drives to spin transition in paramagnetic (Kurie–Weiss) state, and at certain pinch of concentration there is a phase of a spin glass. The nature of this transition contacts a role of interaction Dzjaloshinsky–Moria.
Keywords:
Hund’s rules, spin transitions, Dzyaloshinsky–Moriya interaction.
