The spin crossover phenomenon consists in switching between two spin states of the central ion of a transition 3d- metal in a molecular complex. The spin crossover can be induced and controlled by temperature, pressure, light radiation etc. The prese

In an easy-axis ferromagnet, the effect of superposition of severe plastic deformation by twisting (SPDT) perpendicular to the “easy axis” on the ferromagnetic order parameter (OP) distribution is studied. The consideration is carried out within

The short-range many-body forces induced by the overlap of electron shells of atoms have been investigated. The nonorthogonality of atomic orbitals of the nearest-neighbor atoms of a crystal leads to the appearance of terms in the potential energy, w
