Spin demons in d-wave altermagnets
Demons are a type of plasmons, which consist of out-of-phase oscillations of electrons in different bands. Here, we show that d-wave …

Nonequilibrium effects in spin-torque oscillators
One of the cornerstones of spintronics is the application of a spin-transfer torque to a nanomagnet, driving the magnetization of the …

Charge conservation in spin-torque oscillators leads to a self-induced torque
Spin-torque oscillators are conventionally described by the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation. However, at the onset …

Zero-frequency chiral magnonic edge states protected by nonequilibrium topology
Topological bosonic excitations must, in contrast to their fermionic counterparts, appear at finite energies. This is a key challenge …

Electrical detection of unconventional transverse spin currents in obliquely magnetized thin films
In a typical experiment in magnonics, thin films are magnetized in plane and spin waves only carry angular momentum along their spatial …
