摘要

Magnetic structures in an antiperovskite system, Mn3 Cu1-x Gex N, with a large magnetovolume effect above x=0.15 have been studied by neutron powder diffraction measurement. The present neutron study revealed that not only a cubic crystal structure but also a Γ5g antiferromagnetic spin structure are key ingredients of the large magnetovolume effect in this itinerant electron system. The large magnetovolume effect is possibly ascribed to the geometrical frustration originating from the corner-shared octahedra of the antiperovskite structure.
