Abstract

The pressure (P) derivative of the ferrimagnetic Curie temperature dTc/dP for the Ni2In-type Mn7Sn4-zGez is determined to be dTc/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 Tf 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.
