Change in Neutron Polarization Induced by a Superconductor Rotated in a Magnetic Field J. Phys. I France, Vol. 74.60.Jg - Critical currents.
Depolarization is small if .
In the opposite limit , the depolarization is due to neutron spin rotation about the magnetic flux, which, in turn, rigidly rotates with a superconductor. A total spin reversal is possible at . Depolarization at a stationary rotation angle in a superconducting plate carrying a transport critical current in a magnetic field is considered as well. Depolarisation is determined by either longitudinal or transversal critical currents depending on the angle between the applied field and the critical current direction.
