Resistivity and Magnetism of AMn2P2 (A = Sr, Ba): The Effect of Structure Type on Physical Properties

AMn2P2(A = Sr, Ba) is an example of a composition that can assume a different structure type depending on the identity of the cation. BaMn2P2 crystallizes in the ThCr2Si2 structure type (I4/mmm), and SrMn2P2 crystallizes in the CaAl2Si2 structure type (P3̄m1). Temperature-dependent magnetic susceptibility, neutron diffraction, and resistivity measurements were obtained for the two compounds. Neutron diffraction shows that BaMn2P2 exhibits …
