When angular momentum is conserved, a change in magnetization must thus be accompanied with a change of other forms of angular momentum in the system -- in the Einstein-de Haas Experiment, this was ...

a) In a weak magnetic field, broad cyclotron orbits suppress the orbital contribution, allowing spin polarization to dominate, (b) In strong magnetic fields, tight cyclotron orbits enhance orbital ...

When exposed to intense laser pulses, the magnetization of a material can be manipulated very fast. Fundamentally, magnetization is connected to the angular momentum of the electrons in the material.
