Analytical solutions for ultra-fast precessional switching in inertial magnetization dynamics
Alessandro Fortunati, Massimiliano d'Aquino, Claudio Serpico
Here we consider the magnetization dynamics in ferromagnetic nanoparticles or films driven by external magnetic field pulses directed transverse to the initial equilibrium state. T…

Controlled Quasi-Latitudinal Solutions for ultra-fast Spin-Torque Precessional Magnetization Switching
Alessandro Fortunati, Massimiliano d'Aquino, Claudio Serpico
The aim of the paper is to present a novel class of time-dependent controls to realize ultra-fast magnetization switching in nanomagnets driven by spin-torques produced by spin-pol…
