- This work was the first to identify and explain a new mechanism of vortex core magnetization reversal in hybrid magnetic anisotropy structures, which is vital in understanding failure mechanisms of nano-oscillator devices. Due to the 3D magnetization profile within the structure, this mechanism is fundamentally different from behaviour seen in magnetically homogenous structures. This has influenced research into magnetic vortex dynamics, Bloch points and spin-valve structures utilizing hybrid magnetic anisotropy by groups in leading global institutions including the Lawrence Berkeley National Laboratory (USA) and the Universities of Cambridge (UK), Oxford (UK), Cornell (USA), ETH Zurich (Switzerland), and Western Australia (Australia).
