Abstract

New intermetallic compounds (Mn1-xNix)(65)Ga-35 of Ni2In type structure are found in the range of 0.15 less than or equal to x less than or equal to 0.45. In the higher x range, the magnetization-temperature curves show Curie-Weiss type behaviors, but those with x less than or equal to 0.35 suggestanother type ferromagnet. The magnetic ordering temperature T-c decreases for x less than or equal to 0.2 and then increases with increasing x. The curves of 0.25 less than or equal to x less than or equal to 0.3 show a humpand then slightly decrease with decreasing temperature. In the neutron diffraction experiment for x = 0.275, the (0 0 1) reflection appears for 165 Kless than or equal to T < 218 K indicating the presence of an antiferromagnetic component lying in basal plane. For T < 165 K, the satellite lines of(0 0 1) suggest an appearance of incommensurate phase, perhaps of a helicalspin structure, changing the pitch of helix from 5.78C to 8.47C with temperature.
