Abstract

YBa $_{2}$ Cu $_{3}$ O $_{7}$ - La $_{2/3}$ Sr $_{1/3}$ MnO $_{3}$ heterostructures of [110] orientation are grown to allow direct injection of spin polarized holes from the La $_{2/3}$ Sr $_{1/3}$ MnO $_{3}$ into the CuO $_{2}$ superconducting planes. The magnetic response of the structure at T $<$ T $_{sc}$ shows both diamagnetic and ferromagnetic moments with [001] direction as magnetic easy axis. While the superconducting transition temperature (T $_{sc}$ ) of these structures is sharp ( $Δ$ T $_{sc} ≃$ 2.5 K), the critical current density (J $_{c}$ ) follows a dependence of the type $J_{c} = J_{o} (1 - \frac{T}{T _{sc}})^{3/2}$ with highly suppressed J $_{o}$ ( $≃ 2 \times 1 0^{4}$ A/cm $^{2}$ ) indicating strong pair breaking effects of the ferromagnetic boundary.
