Journal Article
Shepley, P., Rushforth, A., Wang, M., Burnell, G., & Moore, T. (2015). Modification of perpendicular magnetic anisotropy and domain wall velocity in Pt/Co/Pt by voltage-induced strain. Scientific Reports, 5, Article 7921. https://doi.org/10.1038/srep07921

The perpendicular magnetic anisotropy Keff, magnetization reversal, and field-driven domain wall velocity in the creep regime are modified in Pt/Co(0.85–1.0 nm)/Pt thin films by strain applied via piezoelectric transducers. Keff, measured by the extr... Read More about Modification of perpendicular magnetic anisotropy and domain wall velocity in Pt/Co/Pt by voltage-induced strain.

In this paper, we use simultaneous magnetometry and electrical transport measurements to critically examine ways in which the Curie temperature (TC) values have been determined in studies of dilute magnetic semiconductors. We show that, in sufficient... Read More about Determining Curie temperatures in dilute ferromagnetic semiconductors: high Curie temperature (Ga,Mn)As.

Spin-orbit torque opposing the Oersted torque in ultrathin Co/Pt bilayers (2014)
Journal Article
Skinner, T., Wang, M., Hindmarch, A., Rushforth, A., Irvine, A., Heiss, D., …Ferguson, A. (in press). Spin-orbit torque opposing the Oersted torque in ultrathin Co/Pt bilayers. Applied Physics Letters, 104(6), Article 062401. https://doi.org/10.1063/1.4864399

Current-induced torques in ultrathin Co/Pt bilayers were investigated using an electrically driven ferromagnetic resonance technique. The angle dependence of the resonances, detected by a rectification effect as a voltage, was analysed to determine t...
