Low-temperature magnetic properties of a Heisenberg model consisting of ferro- and antiferromagnetic layer superlattices are studied by using spin-wave theory and retarded Green's function method. The four-sublattice magnetizations and internal energy and specific heat at low temperature are...

The method of the effective-field theory with self-spin correlations and the differential operator technique is used to study the magnetic properties of the spin-3/2 Ising model with biaxial crystal-field on the honeycomb lattice. The effects of a biaxial crystal-field described by two uniaxial...

Magnetic properties of a biaxial spin system on the honeycomb and square lattice have been studied based on the effective-field theory with the differential operator technique. The effects of the external longitudinal magnetic field on the magnetization and susceptibility are discussed in...

The mixed spin-12 and spin-32 transverse Ising model with a crystal field is studied within the framework of the effective-field theory with correlations. The phase diagrams and thermal behaviors of magnetizations are investigated numerically for the honeycomb (z=3). The results show that there...

The mixed spin- 1/2 and spin- 3/2 transverse Ising model in a longitudinal magnetic field is studied within the framework of the effective-field theory with correlations. In this approach the effective-field equations are derived by using a probability distribution method based on the...

The Secure Multi-Party Computation (SMC) model provides means for balancing the use and confidentiality of distributed data. This is especially important in the field of privacy-preserving data analysis (PPDA). Increasing security concerns have led to a surge in work on practical secure...
