Magnetic spiral order in the square-lattice spin system (CuBr)SrNbO
A. V. Mikheyenkov, V. E. Valiulin, A. F. Barabanov
We address quantum spin helical states in the strongly frustrated Heisenberg model. Contrary to conventional Dzyaloshinskii-Moriya approach we show that such states appear without…

Thermodynamics of symmetric spin--orbital model: One- and two-dimensional cases
V. E. Valiulin, A. V. Mikheyenkov, K. I. Kugel +1
The specific heat and susceptibilities for the two- and one-dimensional spin--orbital models are calculated in the framework of a spherically symmetric self-consistent approach at…
