Coupling magnetism to superconductivity in thin films
The antagonist electron spin orders in ferromagnetism and in spin-singlet Cooper pairs mediated superconductivity hamper the application of superconductor/ferromagnet (S/F) thin film heterostructures in low power dissipation spintronics because of the low penetration depth of those Cooper pairs in the ferromagnet. However, at carefully engineered S/F interfaces, equal-spin-triplet Cooper pairs with large penetration depth can be generated. This is the case when the ferromagnet shows in-plane magnetic texture like domains , as depicted in the figure.
