Abstract

The Faraday rotation technique is used to map out the finite-temperature phase diagram of the prototypical frustrated magnet ZnCr2O 4, in magnetic fields of up to 190 T generated by the single-turn coil method. We find evidence for a number of magnetic phase transitions, which are well-described by the theory based on spin-lattice coupling. In addition to the 1/2 plateau and a 3 : 1 canted phase, a 2 : 1 : 1 canted phase is found for the first time in chromium spinel oxides, which has been predicted by a theory of Penc et al. to realize in a small spin-lattice coupling limit. Both the new 2 : 1 : 1 and the 3 : 1 phases are regarded as the supersolid phases according to a magnetic analogy of Matsuda and Tsuneto, and Liu and Fisher.
