Abstract

We report on the suppression of critical current in YBa2Cu3Ox thin films by the injection of spin-polarized electrons from colossal magnetoresistive (CMR) materials La0.67Ca0.33MnO3 and La0.67Sr0.33MnO3. We compare the effect of pulse and direct current injection. The gain of such devices and their temperature dependence is reported. We give evidence of the effect of spin polarization and argue that the most favourable conditions for the spin injection could be reached in contacts of sub-micron size.
