Non-equilibrium heating path for utrafast laser-induced nucleation of skyrmion lattices
Pablo Olleros-Rodríguez, Mara S. Strungaru, Sergiu I. Ruta +4
We explore the helicity-independent light-induced nucleation of skyrmion lattices in ferromagnetic cobalt-based trilayers with perpendicular magnetic anisotropy. Using Atomistic Sp…
Modeling coupled spin and lattice dynamics
Mara Strungaru, Matthew O A Ellis, Sergiu Ruta +3
A unified model of molecular and atomistic spin dynamics is presented enabling simulations both in microcanonical and canonical ensembles without the necessity of additional phenom…
Single femtosecond laser pulse excitation of individual cobalt nanoparticles
Tatiana M. Savchenko, Michele Buzzi, Ludovic Howald +12
Laser-induced manipulation of magnetism at the nanoscale is a rapidly growing research topic with potential for applications in spintronics. In this work, we address the role of th…
Hypersonic heat-induced flows of magnons induced by femtosecond laser pulses
Sergiu Ruta, Zuwei Fu, Thomas Ostler +2
In this work, we present evidence for the existence of a magnonic current on the sub-picosecond time-scale in a ferrimagnetic bilayer and its effect on ultrafast spin dynamics. The…
Magnetisation dynamics of granular HAMR media by means of a multiscale model
Andrea Meo, Wasan Pantasri, Wassana Daeng-am +5
Heat assisted magnetic recording (HAMR) technology represents the most promising candidate to replace the current perpendicular recording paradigm to achieve higher storage densiti…
Model of damping and anisotropy at elevated temperatures: application to granular FePt films
Mara Strungaru, Sergiu Ruta, Richard F L Evans +1
Understanding the damping mechanism in finite size systems and its dependence on temperature is a critical step in the development of magnetic nanotechnologies. In this work, nano-…
