In this study the author focuses on thermal and magnetic properties of diluted magnetic semiconductors at critical point. Such properties are discontinuous at some point in the critical region so that it is very important to study their critical behavior in these regions. In orde...

In this paper we show that the generalization of the virial theorem can be achieved for nonrelativistic quantum mechanical systems under the conditions of rotational symmetry and the constancy of the trace of moment of inertia tensor. Under these conditions the matrix elements of...

We synthesized a quasi-two-dimensional Heisenberg antiferromagnet on a square lattice formed in α -RbCrF4 by improving the pretreatment method before primary sintering. From X-ray diffraction measurements, the crystal structure was found to consist of a TlAlF4-type structure, whi...

Kaluza-Klein cosmological model has been obtained in the general theory of relativity. The source for energy-momentum tensor is assumed a perfect fluid. The field equations have been solved by using a special form of the average scale factor proposed by Cai et al. [10]. The phys...

The gamma backscattering is a useful technique in determining effective atomic number of backscattering material. In gamma backscattering technique there is no direct contact with the detector and material under study. So, in the present work the intensity distribution of backsca...

In this article we analyze some logical contradictions of the special relativity theory (SRT), concerning the time dilation and length contraction. The Lorentz transformations and the relativistic law for velocity addition are considered in detail. The notion of relativity and th...
