Interfacial orbital torques excite nanoscale terahertz magnons
Harshita Devda, Peter M. Oppeneer, Ulrich Nowak
Exchange-dominated magnons in nanometer-thick ferromagnets extend to the terahertz regime through thickness quantization of perpendicular standing spin-wave (PSSW) modes. While int…
Quantum fluctuations determine the spin-flop transition in hematite
Tobias Dannegger, Imre Hagymási, Levente Rózsa +1
Magnetic phase transitions between ordered phases are often understood on the basis of semi-classical spin models. Deviations from the classical description due to the quantum natu…
Anatomy of spin-orbit-torque-assisted magnetization dynamics in Co/Pt bilayers: Importance of the orbital torque
Harshita Devda, András Deák, Leandro Salemi +4
Understanding the mechanism driving magnetization switching in spin-orbit-torque-assisted devices remains a subject of debate. While originally attributed to the spin Hall effect a…
Hidden quantum correlations in the ground states of quasiclassical spin systems
Levente Rózsa, Dennis Wuhrer, Sebastián A. Díaz +2
Frustrated spin models may lead to the formation of both classical non-collinear spin structures and unique quantum phases including highly entangled quantum spin liquids. Here, we…
