Y. Irie et al., WEAK FERROMAGNETIC BEHAVIOR CD1-X-YMNXFEYTE (Y-APPROXIMATE-TO-0.01), Journal of magnetism and magnetic materials, 140, 1995, pp. 2027-2028
Temperature dependent magnetic susceptibility and magnetization curve
were obtained for Cd1-x-yMnxFeyTe single crystal. We find weak ferroma
gnetic behavior only in the sample with x = 0.37 at which the electric
al resistivity shows singular behavior. The origin of such weak ferrom
agnetism would be ascribed to the s-d interaction between the band ele
ctron and Fe ion.
