Magnetic excitation spectrum of the Helimagnetic Spinel compound ZnCr2Se4
ZnCr2Se4 is a magnetically frustrated spinel compound with an incommensurate ground state. At low temperatures it displays a spin spiral structure propagating along the (100) crystal directions, and the formation of this state is accompanied by a structural transition, indicating a spin-lattice coupling. With our sample of co-alligned single crystals, we propose to map out the magnetic excitation spectrum of this compound and by doing so quantitatively determine the strength of the magnetic interactions, with the aim of developing a realistic magnetic Hamiltonian for this material. To do this we request 8 days of beamtime on the IN8 spectrometer.
