| Popis: |
The anisotropic polarized spin injection effect on the critical current density Jc of La0.7Sr0.3MnO3/La1.85Sr0.15CuO4 heterostructure is systematically investigated. It is found that the contribution of δTc pinning mechanism is enhanced with spin injection. The angle dependent Jc(θ) near H//c can be scaled by the Ginzburg-Landau (G-L) expression, while for H//ab the intrinsic pinning drives the data to deviate from the G-L fitting. The relative changes of Jc affected by spin injection show opposite variation trends with increasing fields for H//ab and H//c, which is probably related to the different suppressions of injected spins on different flux pinnings. |
