We used mean-field theory based on the Bogoliubov inequality for the Gibbs free energy to examine the mag-
netic properties of a mixed spin-5/2 and spin-7/2 Blume-Capel ferrimagnetic system. The thermal behaviours
of the system magnetization are cl [...]

We use standard Monte Carlo simulations based on the Metropolis algorithm and mean-field calculations to investigate
the magnetic properties of an Ising bilayer film consisting of two superposed ferromagnetic squared lattices A and B
whose magnetic [...]

We use theoretical and numerical calculations in the framework of the effective-field
theory to examine the rigorous effects of the crystal field interactions of the mixed
spin-2 and spin- 32 Blume–Capel model on the honeycomb lattice in the presen [...]

The Brinkman model is used to study the criterion of appearance of station-
ary convection in a porous horizontal layer saturated by a binary mixture of
ferrofluids and heated from below. The analytical expression of the Rayleigh
number is determi [...]

In this paper we studied the onset of instability in a horizontal layer of a rotating ferrofluid in the
presence of the helical force. The analytical expression of the Rayleigh number of the system is
determined as a function of the dimensionless n [...]

Stability characteristics of the flow of incompressible viscous fluid, subjected to a uniform magnetic field are investi-
gated. The temporal evolution of infinitesimal perturbations is performed by spectral computation of Navier-Stokes
equations. [...]

In this paper, a fractal Josephson junction with unharmonic current-phase relation is analytically and numerically analyzed. This system
has two, four, or no equilibrium points depending on the external direct current source and unharmonic parameter [...]
