- Spin orbit torque (SOT) induced magnetic random access memory is an emerging memory which promises to rival semiconductor memories. Besides memories, an understanding of SOT effects is crucial for magnetisation reversal mediated devices. In magnetic materials with perpendicular magnetic anisotropy (PMA), the effect of in-plane magnetisation tilt, a natural side-effect of device patterning, is unknown, due to complicated nature of SOT. Here, a mathematical framework for calculating and interpreting SOT effective fields as a function of in-plane magnetisation tilt is presented and experimentally validated. This work establishes a platform for the standardisation of characterising SOT in PMA materials.
