摘要：

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) mu(B). Below 3 K, LaCrGe3 has a spin-canted ferromagnetic structure with a canting angle theta of 32(6)degrees and a Cr magnetic moment of 1.31(4) mu(B) at 1.7 K.
