In particular, the representation of the temperature dependence in terms of the
sublattice magnetization or of the exchange fields in the decoupled-sublattice
version has to be re-examined, while the basic assumption of the single-ion ...

Temperature dependence of the pinning parameter coefficients a, aft, at and a for
the film shown in fig. 12. For YIG D & 10-4” erg cm" and, since the unit cell has
two equivalent magnetic sites, a = 9.84A and S = 4(3) = 10. Then b, + 6.43a; erg ...
