We also discovered a new type of magnetoresistance (MR) in nominally nonmagnetic metal (Pt) thin films in contact with a ferromagnet (FM), either insulating such as YIG, or metallic such as permalloy (Py). The new MR depends on the direction of the magnetization of the underlying FM as aligned by an external magnetic field. The resistivity of Pt/YIG with in-plane YIG magnetization parallel (ρ||) or transverse (ρT) to the current, and with an out-of-plane YIG magnetization (ρ^) perpendicular to the current shows the behavior of ρ^ ≈ ρ|| > ρT, distinctively different from all previous known MR effects, including the well-known anisotropic MR in polycrystalline FMs of ρ|| > ρT ≈ ρ^.  More recently, we showed the different mechanisms that contribute to the new MR, impacting the theoretical proposals for the new MR.
