Magnetic properties of new compounds RuMn2Sn and RuMn2Si
Abstract New compounds RuMn 2 Z (Z = Si, Sn) have been synthesized. X-ray diffraction measurements have confirmed that RuMn 2 Z (Z = Si, Sn) crystallizes in a Heusler-like cubic structure. The lattice parameters of RuMn 2 Si and RuMn 2 Sn at room temperature are estimated to be 5.8260 A and 6.2195 A, respectively. Magnetization measurements have been carried out in fields up to 50 kOe for RuMn 2 Z (Z = Si, Sn). Furthermore, the temperature dependence of initial permeability of RuMn 2 Sn has been studied. RuMn 2 Sn shows ferrimagnetic behavior. The spontaneous magnetic moment at 5 K and the Curie temperature of RuMn 2 Sn are found to be of 1.68 μ B /f.u. and 272.1 K, respectively. RuMn 2 Si exhibits spin-glass-like behavior with a freezing temperature estimated to be about 50 K.
