Abstract
YBa2Cu3O7-La2/3Sr1/3MnO3 heterostructures of [110] orientation are grown to allow direct injection of spin polarized holes from the La2/3Sr1/3MnO3 into the CuO2 superconducting planes. The magnetic response of the structure at T<Tsc shows both diamagnetic and ferromagnetic moments with [001] direction as magnetic easy axis. While the superconducting transition temperature (Tsc) of these structures is sharp (Δ Tsc ⋍ 2.5 K), the critical current density (Jc) follows a dependence of the type Jc = Jo(1-T/Tsc)3/2 with highly suppressed Jo( ⋍ 2×104 A/cm2), indicating strong pair breaking effects of the ferromagnetic boundary.
