Pseudobinary intermetallic compounds (Mn[SUB1-x]Pd[SUBx])[SUB2]Ga of Ni[SUB2] In type structure are found in the range of 0.3 ≦ x < 0.6. This article describes the results of investigations of the crystal and magnetic properties of the phase with x-ray and neutron diffraction, as well as magneto metric methods. The neutron diffraction study for x = 0.4 proved that in the Ni[SUB2] In type crystal structure, the 2(a) site is occupied by Mn atoms, the 2(d) site by Pd and residual Mn atoms, and the 2(c) site is occupied by Ga atoms. (Mn[SUB1-x]Pd[SUBx])[SUB2]Ga compounds exhibit a ferromagnetic nature characterized by T[SUBC], and in the temperature below T[SUBN], antiferromagnetic components originating from canted spin structure in 2(a) structures in the 2(a) site. It is similar to canted spin structures of CoMnSn. The existence of a small concave region in the magnetization-temperature dependence curve is discussed in terms of the canting of spins in the 2(a) site. [ABSTRACT FROM AUTHOR] |
