Electrical control of spin dynamics in spin-orbit coupled ferromagnets
… In materials with broken inversion symmetry and spin-orbit coupling, electrical current can exert a torque on a local magnetisation. In the studies presented here, a microwave current-induced ferromagnetic resonance (spin-orbit FMR) technique is used to characterise the dynamical magnetic …

IN THE SPIN
<p>In the Spin is a semi-autobiographical collection of poetry, dealing primarily with themes of family, marital infidelity, loyalty, the female body, and the tension between political vs. aesthetic existence. This is a collection of poems influenced by the work of French Feminism, Shakespeare and …

Thermal Effects on Spin Currents in Non-Local Metallic Spin Valves
<p>The study of non-local spin valves (NLSVs) has recently proven to be a fertile area for both applied and fundamental research in nanomagnetism due to the unique ability to separate charge currents and spin currents. NLSVs may also prove essential for a new class of high-density hard disk read …
