Three-dimensional (3D) antiferromagnets are materials in which magnetic moments of atoms or ions are arranged in a 3D lattice structure with neighboring spins aligned in opposite directions. Physicists have observed a fascinating ...
A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet—a technique that could eventually lead to the development of more ...
