Magnetic excitations in AgCrSe2

AgCrSe2 has emerged as a material of great interest due it its good thermoelectric performance. It also has an interesting cycloidal magnetic structure. While studying the thermoelectric parameters we have discovered that the previously published magnetic interactions are inconsistent with the magnetic structure. We now propose to study the magnetic excitations to higher energy than have previously been possible using MAPS which will allow us to resolve this.

硒化铬银（AgCrSe2）凭借其优异的热电性能，已成为广受关注的研究材料，同时其还具备引人关注的旋摆磁结构（cycloidal magnetic structure）。本团队在研究热电参数的过程中发现，已有文献报道的磁相互作用与该材料的磁结构并不一致。为此，我们提出利用MAPS开展能量范围高于以往的磁激发研究，以此解决这一矛盾。
