Neutron Diffraction Study of the Hexagonal Perovskite-Type Compound LaCrGe₃

Abstract:

The BaNiO₃-type structure and the ferromagnetic order (T_C = 78 K) of the Cr sublattice in LaCrGe₃ have been confirmed by neutron powder diffraction measurements. At 20 K, the magnetic structure is collinear along the c axis with a Cr magnetic moment of 1.24(4) μ_B. Below 3 K, LaCrGe₃ has a spin-canted ferromagnetic structure with a canting angle θ of 32(6) and a Cr magnetic moment of 1.31(4) μ_B at 1.7 K.
