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.
