Anisotropic Heisenberg model for the mixed spin-3/2 and spin-1/2 under random crystal field
D. Sabi Takou, M. Karimou, F. Hontinfinde +1
Thermodynamic properties of the mixed spin-3/2 and spin-1/2 Heisenberg model are examined within the Oguchi approximation in the presence of a random crystal-field (RCF). The RCF i…
Phase diagrams and critical behaviours of the mixed spin-5/2 and spin-7/2 Ising system
M. Karimou, R. A. Yessoufou, G. Dimitri Ngantso +2
We used mean-field theory based on the Bogoliubov inequality for the Gibbs free energy to examine the magnetic properties of a mixed spin-5/2 and spin-7/2 Blume-Capel ferrimagnetic…
Bethe lattice approach study of the mixed spin- and spin- Ising model in a longitudinal magnetic field
S. Eddahri, M. Karimou, A. Razouk +2
The magnetic properties of the mixed spin- and spin- Ising model with a crystal-field in a longitudinal magnetic field are investigated on the Bethe latti…
Bethe approach study of the mixed spin-1/2 and spin-5/2 Ising system in the presence of an applied magnetic field
M. Karimou, R. A. Yessoufou, T. D. Oke +2
The mixed spin-1/2 and spin-5/2 Ising model is investigated on the Bethe lattice in the presence of a magnetic field via the recursion relations method. A ground-state phase di…
Numerical study of the spin-3/2 Ashkin-Teller model
R. Boudefla, S. Bekhechi, F. Hontinfinde
The study of the Ashkin-Teller model (ATM) of spin-3/2 on a hypercubic lattice is undertaken via Monte Carlo simulation. The phase diagrams are displayed and discussed in the physi…
