Phase diagram of the spin Blume-Capel model in random single-ion anisotropy and magnetic field revisited

We used the Curie-Weiss mean-field approximation to study the effects of random single-ion anisotropy and random magnetic field in the phase diagram as well as in the thermodynamic properties of the spin-7/2 Blume- Capel model. The phase diagrams are presented in the planes temperature versus single-ion anisotropy and temperature versus magnetic field, temperature versus random parameters. The dependencies of magnetization are studied as a function of temperature and single-ion anisotropy.

Automated summary

The effects of random single-ion anisotropy and random magnetic field on the phase diagram and thermodynamic properties of the spin-7/2 Blume-Capel model were investigated using the Curie-Weiss mean-field approximation. Phase diagrams were presented in the temperature versus single-ion anisotropy, temperature versus magnetic field, and temperature versus random parameters planes. The dependencies of magnetization on temperature and single-ion anisotropy were studied.
