Anisotropic spin-orbit interaction revealed by in-plane magnetoresistance in single-oriented SrRuO3 thin films

Artikel i vetenskaplig tidskrift, 2012

A detailed analysis of the in-plane magnetoresistance anisotropy in single orientation thin film SrRuO3 grown on (001)SrTiO3 is presented. The resistivity is measured in strips along [001], [¯110] and [¯11¯1] with in-plane rotating magnetic field. The data show new details in the transfer from negative to positive magnetoresistance when the field is rotated in the plane. They show that the magnetoresistance is anisotropic with respect to the crystalline directions rather than with respect to the direction of the current. The data suggest an
