Abstract

The pressure (P) derivative of the ferrimagnetic Curie temperature dT_c/dP for the Ni2In-type Mn₇Sn_4-zGe_z is determined to be dT_c/dP=(1.8±0.1)—(0.4±0.1)z K/kbar. The signs of the pressure derivatives dPf/dP are negative for z=0 and 0.4, where T_f is the transition temperature from the spin-glass like state to the ferrimagnetic one. These pressure effects are discussed on the basis of the interaction curve for antiferromagnetic Mn alloys.
