Magnetic Properties of the low dimensional BaM${}_2$Si${}_2$O${}_7$(M= Cu, Co, Mn) system

Abstract

We performed susceptibility, magnetization, specific heat, and single crystal neutron diffraction measurements on single crystalline BaMn${}_2$Si${}_2$O${}_7$. Based on the results, we revisited its spin structure with a more accurate solution and constructed a magnetic phase diagram with applied field along the $b$-axis, which contains a spin flop transition around 6 T. We also used susceptibility, magnetization, and specific heat results confirmed the ferrimagnetic-like magnetism in polycrystalline BaCo${}_2$Si${}_2$O${}_7$. Furthermore, we performed LSDA + U calculations for the BaM${}_2$Si${}_2$O${}_7$ (M = Cu, Co, and Mn) system. Our discussions based on the comparison among the obtained magnetic exchange interactions suggest the different structures and electronic configurations are the reasons for the different magnetic properties among the system members.
