The degree of anisotropy of these lowest levels thus is a clear indication for the
magnitude of anisotropic phenomena such as magnetic anisotropy ,
magnetostriction , or relaxation mechanisms . If we apply the Hamiltonians given
in sect .

The two lowest levels behave like a magnetic doublet , which , in addition , is well
separated from the higher levels . In contrast to the Co2 + ions , near crossings of
the lowest levels , which induce sharp peaks in the field for ferromagnetic ...

The rare - earth ions give rise to the highest anisotropies in garnets , which is
reflected by their energy level diagram . A very typical example is the terbium ion
. The angular variation of its energy levels shows a pronounced structure , as can
...
