Magnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice

H. Mohammadi Kamrava, M. Barati

Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization, internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.

The trimodal random-field Ising model with the presence of a transverse field is investigated by introducing a parameter p to simulate the fraction of spins not exposed to the external longitudinal magnetic field. Phase diagrams are obtained for different cases, and conditions for the occurrence of tricritical and reentrant phenomena are found. The competing effects on phase transitions due to the magnetic randomness and quantum fluctuations are also discussed.
