High-field neutron diffraction investigation on the field induced spin super-fluid and super-solid states of MnCr2S4.
MnCr2S4 is a bond-frustrated spinel compound with magnetic Mn3+ and Cr3+ ions. It has attracted immense interest in recent years for showing extremely rich magnetic phase diagram. MnCr2S4 undergoes two magnetic transitions:(i) at T_c = 65 K to a ferrimagnetic state and (ii) at T_YK = 5 K to a canted-spin state known as Yafet-Kittel (YK)type phase. Recent single crystal magnetization and ultrasound experiments by Tsurkan et al. (one of the co-proposers) up to 60 T between 1.5 K and 28 K revealed that under the influence of an external magnetic field, MnCr2S4 exhibits a manifold of competing spin states which can be described as spin-superfluid and spin-supersolid phases. To extract direct information about the field induced magnetic structure, we have successfully performed single crystal neutron diffraction measurements up to 26 T on MnCr2S4. We now aim to perform diffraction up to 40 T using pulsed-field to get information about the spin-structure in the higher field regime.
