As the core ingredient for spin polarization, local equilibrium distribution function is derived from detailed balance principle. The kinetic theory interacting fermionic systems applied to Nambu--Jona-Lasinio model at quark level. Under semi-classical expansion with respect $\hbar$ and non-perturbative $N_c$, equations vector axial-vector functions are collision terms. It found that, an initia...

  In this research, a low temperature in-field 57Fe Mössbauer spectroscopy is used for investigation of anomalous magnetic properties of MnZn nanoferrite. Based on Mössbauer spectroscopy results, the reduced saturation magnetization of MnZn nanoferrite in respect to that of bulk sample is due to nonequilibrium cation distribution and spin disorder. The enhanced Curie temperature of MnZn nanofer...

In a superconductor coupled with a ferromagnetic metal, spin and charge imbalances can be induced by injecting spin-polarized electron current from the ferromagnetic metal. We theoretically study a nonequilibrium distribution of quasiparticles in the presence of spin and charge imbalances. We show that four distribution functions are needed to characterize such a nonequilibrium situation, and d...

Boundary conditions are derived that determine the penetration of spin current through an interface of two non-collinear ferromagnets with an arbitrary angle between their magnetization vectors. We start from the well-known transformation properties of an electron spin wave functions under the rotation of a quantization axis. It allows directly find the connection between partial electric curre...

The spin densities of the nitroxides H 2 N O , (CH 3 )HNO and (CH 3 ) 2 NO have been studied by iterative CI methods. Calculations at different geometries with various basis sets were performed. It is found that the spin distribution is delocalized within the N O group, and substitution of the hydrogen atoms on the nitroxyl group by methyl groups changes the spin distribution significantly. Ele...

We prove the existence of a stable solution of the renormalized fixed point equation for the distribution of the single-site magnetization in the Bethe lattice spin glass at zero temperature. The proof is computer assisted. RESUME. Nous prouvons 1’existence d’une solution stable de l’équation de point fixe de renormalisation pour la distribution de la magnétisation d’un spin dans Ie modele de v...
