Persistent magnetic coherence in magnets

Nature Materials
When excited, the magnetization in a magnet precesses around the field in an anticlockwise manner on a timescale governed by viscous magnetization damping, after which any information carried by the initial actuation seems to be lost. This damping appears to be a fundamental bottleneck for the use of magnets in information processing.

Magnetic Neurosurgery

Stereotactic and Functional Neurosurgery, 1996
Because of the complex shape of many brain structures, the ideal brain probe would be highly flexible and give the neurosurgeon the ability to independently and precisely control movement of the probe tip. A magnetic surgery system has been developed that implements this concept.

Switching of perpendicular magnetization by spin-orbit torques in the absence of external magnetic fields.

Nature Nanotechnology, 2013
Magnetization switching by current-induced spin-orbit torques is of great interest due to its potential applications in ultralow-power memory and logic devices. The switching of ferromagnets with perpendicular magnetization is of particular technological

Magnetic Monopoles in a Magnetic Universe

1984
Large scale coherence of a cosmological magnetic field, independently of its strength, is incompatible with any detectable monopole flux. Consequently, the controversial evidence1 of a coherent magnetic field up to a redshift z ≃ 2 infers the most severe cosmological bound on present number density (no) and fluxes (F) of magnetic monopoles: \( n_O < 2 \
