Phase diagram of the spin-1 XXZ Heisenberg ferromagnet with a single-ion anisotropy
Jozef Strecka, Jan Dely, Lucia Canova
Phase diagram of the spin-1 quantum Heisenberg model with both exchange as well as single-ion anisotropy is constructed within the framework of pair approximation formulated as a v…

Phase diagram of the spin-1 anisotropic Heisenberg model with a single-ion anisotropy
Jan Dely, Jozef Strecka, Lucia Canova
The spin-1 anisotropic Heisenberg model with a single-ion anisotropy is studied using the Oguchi's pair approximation. Although the theory is developed for lattices with general co…
