Self-modulation instability in high power ferromagnetic resonance of BiYIG nanodisks
Igor Ngouagnia Yemeli, Salvatore Perna, Diane Gouéré +9
We study the high power ferromagnetic resonance (FMR) of perpendicularly magnetized BiYIG nanodisks where the uniaxial anisotropy almost compensates the shape anisotropy. We observ…
Quantum Micromagnetic Theory of Magnons in Finite Nanostructures
Claudio Serpico, Salvatore Perna, Massimiliano d'Aquino
This paper presents a quantum field theoretical formalism for studying magnons in finite nanostructures with arbitrary shapes and spatially nonuniform ground states. It extends the…
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…
Mode-resolved micromagnetics study of parametric spin wave excitation in thin-film disks
Maryam Massouras, Salvatore Perna, Massimiliano d'Aquino +2
We present a computational study of the parametric excitation of spin waves in thin film disks with a mode-resolved approach. The method involves projecting out the time-dependent…
