Description

MnSc2S4, a magnetically frustrated thiospinel with Mn forming a diamond lattice, shows multistep long-range ordering as a function of applied field, H and temperature, T [1]. We used neutron scattering to map the H(T), T(K) phase boundaries of the triple-k state for the magnetic field applied along (111) and (110) crystallographic directions and Monte Carlo simulations to examine the additional terms in the spin Hamiltonian, e.g. single ion anisotropy and exchange anisotropy that stabilize this fractional skyrmion topological state.
