Lagrangian approach in spin-oscillations problem
Lagrangian of electronic liquid in magneto-inhomogeneous micro-conductor has
been constructed. A corresponding Euler-Lagrange equation has been solved. It
was shown that the described system has eigenmodes of spin polarization and
total electric current oscillations. The suggested approach permits to study
the spin dynamics in an open-circuit which contains capacitance and/or
inductivity.Comment: 4 pages, 3 figure
Evolution of vacancy pores in bounded particles
In the present work, the behavior of vacancy pore inside of spherical
particle is investigated. On the assumption of quasistationarity of diffusion
fluxes, the nonlinear equation set was obtained analytically, that describes
completely pore behavior inside of spherical particle. Limiting cases of small
and large pores are considered. The comparison of numerical results with
asymptotic behavior of considered limiting cases of small and large pores is
discussed.Comment: 25 pages, 10 figure
