摘要
The low temperature magnetic structure of Mn2SiSe4 is shown to consist of antiferromagnetically coupled planes of spins with an easy axis parallel to the c-axis. A weak spontaneous magnetization and diffuse scattering observed at T less than or equal to 66(2) K suggest that the spins are canted in a locally ordered manner. This spin configuration gives a new example of how B(II) moments may order within the B(2)AX(4) (A = Si, Ge; X = O, S, Se) olivine structure.
