It is shown that in nonequilibrium superconductors new states with spontaneous spin polarization of quasiparticles can exist due to the Fermi-liquid exchange interaction. The stability o) r both polarized and unpolarized nonequilibrium states with respect to small and finite fluctuations is discussed.It is shown that the nonequilibrium states of superconductors generated by the pumping of quasiparticles may be unstable with respect to both unpolarized and polarized finite fluctuations.

“…(9) and (25), we can easily see that our theory explains the experiments qualitatively well: With large values of r/res, corresponding to T < T~, N, becomes large and we may expect the first-order transition to the normal state. When the temperature exceeds T~, the ratio z/zr becomes small, and the transition to the inhomogeneous state becomes favorable.…”

We discuss the phase transitions induced by the injection of quasiparticles in nonequilibrium superconductors, based upon the equations of Scalapino andHuberman and including nonlinear effects. When the effect of the reaction of quasiparticles with phonons is small the system shows a first-order transition to an inhomogeneous state. As the effect of the reaction becomes larger, the transition becomes of second order. When the effect of the reaction is further increased, the system shows the first-order transition to the homogeneous normal state as was predicted by Owen and Scalapino. The results are in qualitative agreement with the recent experiments of IguchL The relation of the present problem to the spinodal decomposition is discussed.

“…The probability of a solution A is given by W(A)a exp (-, , and a transition between A 1 and A 3 can take place. With increasing total current, the size of the region in the A 1 "phase" with small injection current density decreases in favour of the region in the A 3 "phase" with large injection current density. At high enough voltages, the 43 "phase" is globally stable.…”
