Persistent magnetic coherence in magnets
Nature MaterialsWhen 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.

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.

Magnetic Monopoles in a Magnetic Universe
1984Large 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 \
