Unconventional long range triplet proximity effect in planar YBa_2Cu_3O_7/La_0.7Sr_0.3MnO_3/YBa_2Cu_3O_7 Josephson junctions

The proximity effect between superconductors and ferromagnets may become long range due to the generation of triplet pairs. The recent finding of a long, one micron-range unconventional Josephson effect between YBa_2Cu_3O_7 high Tc cuprates separated by a half metallic La_0.7Sr_0.3MnO_3 manganite fe...
