Spin behavior in a quarter rotation of the magnetic field

The spin rotation of a particle after a quarter rotation of an external magnetic field is calculated numerically and discussed both in the adiabatic and the nonadiabatic schemes. Adding to the well-known fully adiabatic case, we find that the spin rotates a quarter turn along the magnetic field's direction when the transient time of the magnetic field matches closely but not exactly the Larmor precession period or its multiples.
