摘要：

It is shown that the recently discovered giant negative magnetoresistance (GMR) effects in ferromagnetic La1âxMxMnO3 (M=Ca,Sr,Ba) are compatible with the existence of high Tc superconductivity in câaxis oriented YBa2Cu3O7/La0.67Ba0.33MnO3 superlattices. From magnetoresistivity measurements we deduce that above Tc the giant GMR persists up to room temperature. Below Tc the superlattices show a quasiâtwoâdimensional superconductivity of the YBa2Cu3O7 layers coexisting with magnetism in the La0.67Ba0.33MnO3 layers. © 1995, American Institute of Physics.
