Unidirectional magnetoresistance in magnetic thin films with non-uniform thickness

Thickness dependence of magnetic blocking in granular thin films

Precise Measurement of Thickness Distribution of Non- Uniform Thin Films by Imaging Spectroscopic Reflectometry

− A new method of imaging spectroscopic photometry enabling us to perform the complete optical characterization of thin films exhibiting area non-uniformity in optical parameters is presented. An original imaging spectroscopic photometer operating in the reflection mode at normal incidence is used to apply this method. A CCD camera serves as a detector in this photometer. Therefore the spectral...

Anomalous, hysteretic, transverse magnetoresistance in superconducting thin films with magnetic vortex arrays

We have studied a superconducting/ferromagnetic hybrid system in which the normal to superconducting phase transition is controlled by the magnetic history. An anomalous transverse resistance appears at the phase transition, which shows magnetic hysteresis and a strong current dependence. We show that the anomaly originates from current redistributions due to the inhomogeneous superconductivity...

Thickness Dependence of Magnetic Blocking in Granular Thin Films with Interacting Magnetic Particles

Observation of spin-orbit magnetoresistance in metallic thin films on magnetic insulators

A magnetoresistance (MR) effect induced by the Rashba spin-orbit interaction was predicted, but not yet observed, in bilayers consisting of normal metal and ferromagnetic insulator. We present an experimental observation of this new type of spin-orbit MR (SOMR) effect in the Cu[Pt]/Y3Fe5O12 (YIG) bilayer structure, where the Cu/YIG interface is decorated with nanosize Pt islands. This new MR is...
