Estimation of Self-Injection Length in Heterostructures of YBa2Cu3O7-δ Superconductor and La0.67Ca0.33MnO3 Manganite
Epitaxial bilayers of YBa2Cu3O7-δ (YBCO) and La0.67Ca0.33MnO3 (LCMO) heterostructures have been prepared by pulsed laser deposition technique, the growth sequence being YBCO on LCMO. The length scale of the YBCO layer, which is rendered non-superconductor/insulator by selfinjection of the spin polarized quasiparticles, is estimated to be 850Å. This can be an important guiding parameter in spintronic device configuration/fabrication.
