Ultrafast spontaneous spin switching in an antiferromagnet
Marvin A. Weiss, Andreas Herbst, Julius Schlegel +8
Owing to their high magnon frequencies, antiferromagnets are key materials for future high-speed spintronics. Picosecond switching of antiferromagnetic order has been viewed a mile…
Polarized phonons carry the missing angular momentum in femtosecond demagnetization
S. R. Tauchert, M. Volkov, D. Ehberger +8
Magnetic phenomena are ubiquitous in our surroundings and indispensable for modern science and technology, but it is notoriously difficult to change the magnetic order of a materia…
Terahertz spin dynamics driven by an optical spin-orbit torque
Ritwik Mondal, Andreas Donges, Ulrich Nowak
Spin torques are at the heart of spin manipulations in spintronic devices. Here, we examine the existence of an optical spin-orbit torque, a relativistic spin torque originating fr…
Non-collinear antiferromagnetic states in Ru-based Heusler compounds induced by biquadratic coupling
Eszter Simon, Andreas Donges, László Szunyogh +1
We investigate the magnetic properties of RuMn ( = Sn, Sb, Ge, Si) chemically ordered full Heusler compounds for zero as well as finite temperatures. Based on first pri…
Unveiling domain wall dynamics of ferrimagnets in thermal magnon currents: competition of angular momentum transfer and entropic torque
Andreas Donges, Niklas Grimm, Florian Jakobs +4
Control of magnetic domain wall motion holds promise for efficient manipulation and transfer of magnetically stored information. Thermal magnon currents, generated by temperature g…
Terahertz spin dynamics driven by a field-derivative torque
Ritwik Mondal, Andreas Donges, Ulrike Ritzmann +2
Efficient manipulation of magnetization at ultrashort time scales is of particular interest for future technology. Here, we numerically investigate the influence of the so-called f…
