abstract = "We have studied the voltage-current characteristics in La 0.7Ca0.3MnO3/YBa2Cu 3Oy/Au, ferromagnet/superconductor/nonmagnetic metal, double tunnel junctions. Near Tc, the tunnel conductance G(V) reveals a step-like decrease, which can be ascribed to the phenomenon of the phase transition from superconducting state to normal one caused by the spin accumulation effect. With decreasing temperature T, the step in G(V) changes to the sharp peak. Our results indicate that the spin-injection-induced phase transition has a nature of a first order transition at low T.",
