Nanocrystalline epsilon and eta electron compounds and supersaturated solid solution of the Cu-Sn system have been prepared by mechanical alloying of elemental Cu and Sn powders. The atomic alloying and microstructure of the resultant alloys have been investigated by XRD, DSC and Sn-119 Mossbauer sp...

Physica Status Solidi B-Basic Research
The magnetic properties of diluted mixed spin-1/2 and spin-1 Ising magnetic systems with crystal-field interactions on square lattice (z = 4) are investigated by the use of the effective-field theory with correlations. Especially the numerical results are given. The influence of concentrations of ma...

The structure and magnetostriction of R0.5Pr0.5Fex, (R = Dy0.7Tb0.3; 1.10 less than or equal to x less than or equal to 1.85) alloys were investigated. It was found that the matrix of are-melting R0.5Pr0.5Fex, alloys is the (Dy, Tb, Pr) Fe-2 phase with the MgCu2-type cubic structure and the second p...

The influence of a bath consisting of both conduction electrons and Debye phonons on quantum tunneling in metals is studied by the perturbation approach developed by the authors. We find that the renormalized tunneling parameter and the condition of localization transition are modified in comparison...
