(U, Nd)S: Magnetic Susceptibility and Magnetic Phase Diagram

The magnetic susceptibility measurements have been made on antiferromagnetic compounds Mn1–xFexSn2 and the magnetic phase diagram was illustrated. The high temperature magnetic phases I and III, major phases, were analyzed on the basis of molecular field theory and explained the change of magnetic structure I⇌III occured at x≈0.8.

High precision measurements of magnetoresistance =f(T,H) and magnetization M(T,H) have been carried out on single crystals of rare earth dodecaboride TmB12 at temperatures 1.8–30 K in magnetic fields up to 80 kOe. The high accuracy measurements and precise temperature stabilization allowed us to perform numerical differentiation and analyze quantitatively a behavior of derivative d()/dH=f(T,H) and magnetic susceptibility (T,H)=dM/dH in paramagnetic and magnetically ordered phases of thulium dodecaboride. It was shown that negative magnetoresistance anomalies observed in present study in paramagnetic state of TmB12 can be consistently interpreted in frameworks of a simple relation between resistivity and magnetization - /M2 proposed by K. Yosida (Phys. Rev., 107, 396 (1957)). A local magnetic susceptibility loc(T,H)=(1/H(d(/)/dH))1/2 was deduced directly from the magnetoresistance measurements and compared with bulk susceptibility (T,H)=dM/dH results of the present study. Moreover, the susceptibility dependences loc(T,H) and (T,H) have been applied to analyze in detail the H-T magnetic phase diagram of TmB12.

Thermal Variation

Thermal variation of the magnetic susceptibility for Ti-Co solid solutions is reported. Cobalt, by alloying acts on the transition Néel temperature giving rise to a complicated magnetic phase diagram. The change of the Fermi level is the main mechanism in the critical temperature, T N , shift.

Series Expansions

The ferrimagnetic spinels systems Co x Fe 1-x Cr 2 S 4 has been studied by high-temperature series expansions method in the range 0 ≤x ≤1. The exchange interactions and exchange energies are calculated by using the probability law. The high-temperature series expansions have been applied in the spinels systems Co x Fe 1-x Cr 2 S 4, combined with the Padé approximants method, to determine the magnetic phase diagram, i.e., TC versus dilution x. The critical exponent associated with the magnetic susceptibility (γ) is deduced.
