Research Abstract

Magnetic properties for 3d-4d transition metal alloys,(Fe, Mn)(Rh, Pd) system and for Fe(Si, Ge) system were investigated by 57Fe Mossbauer effect measurements and magnetization measurements. A large magnetocaloric effect would be observed for the latter system by electronic structures calculations. For(Fe, Mn)(Rh, Pd) system, we obtained the magnetic phase diagram corresponding to the calculations. For Fe(Si, Ge) system, the obvious change of 57Fe Mossbauer spectra from Kondo insulator to ferromagnetic metal cannot be observed at a critical concentration x_c & sime ; 0.25. The 57Fe hyperfine fields for x=0.6 and 0.7 estimated by fitting of Mossbauer spectra at 80K are 6.0T and 8. 0T, respectively, while they are almost zero for 0≦x≦0. 5.
