Spin waves are collective oscillations of electron spins in magnetic materials. They represent a quantum mechanical phenomenon in which electrons’ angular momentum or spin fluctuates in a coordinated ...
Artificial intelligence is colliding with a hard physical limit: the energy and heat of today’s silicon-based chips. As models grow from billions to trillions of parameters, the bottleneck is no ...
The kagome ferromagnet, Fe₃Sn 2 hosts spin waves - magnetic ripples arising from collective excitations of electron spins (shown here as golden arrows). The new findings reveal that the spin-waves are ...
