Description |
The spin-polarized current injection (SPCI) experiments, where the spin-polarized current (IS) is injected into a 25 μm wide superconducting NbN bridge from a ferromagnetic Co2MnSi layer by tunneling through MgO barrier, show a large (≈67%) suppression of superconducting critical current (IC) due to IS injection at T/TC ≈ 0.4. This corresponds to a large dynamic gain of ≈36 at 3 K, which is 40 times higher than the gain at 6.5 K. Such a rapid rise of gain at lower temperatures strongly suggests a dominant role of SPCI in IC suppression as compared to the effect of Joule-heating.
