Bethe approach study of the mixed spin-1/2 and spin-5/2 Ising system in the presence of an applied magnetic field
The mixed spin-1/2 and spin-5/2 Ising model is investigated on the Bethe lattice in the presence of a magnetic field h via the recursion relations method. A ground-state phase diagram is constructed which may be needful to explore important regions of the temperature phase diagrams of a model. The...

| description |
The mixed spin-1/2 and spin-5/2 Ising model is investigated on the Bethe lattice in the presence of a magnetic
field h via the recursion relations method. A ground-state phase diagram is constructed which may be needful
to explore important regions of the temperature phase diagrams of a model. The order-parameters, the corresponding response functions and internal energy are thoroughly investigated in order to typify the nature of
the phase transition and to get the corresponding temperatures. So, in the absence of the magnetic field, the
temperature phase diagrams are displayed in the case of an equal crystal-field on the (kBT /|J|, D/|J|) plane
when q = 3, 4, 5 and 6. The model only exhibits the second-order phase transition for appropriate values of
physical parameters of a model. |
