Abstract:

Field-induced transitions were studied in Mn3GaC in magnetic fields up to 370 kOe. The antiferromagnetic (AFM)-ferromagnetic (FM) field-induced transition is of the first order. The saturation magnetization sigma(s) at 4.2 K in the FM state is 75.0 emu g(-1) equivalent to 1.1 mu(B) per Mn atom. The decreasing rate of sigma(s) is rather smaller than that of the S = 1/2 Brillouin function. In the magnetostriction measurement of Mn3GaC, an abrupt volume contraction of -0.50\% was found at the AFM-FM transition temperature. The result of the forced volume magnetostriction measurement shows that sigma(s) at 4.2 K increases with pressure. (C) 1997 Elsevier Science Ltd.
