If, on the other hand, the aniso- tropy were weak, as is not unlikely for iron (111) ions, the exchange interactions would impose the type of magnetic ordering,

In a simple model we show that concentration fluctuations need not be accompanied by order parameter fluctuations and that the range of instability, the critical wave length and

This Fe - Cu interaction near the inter- face also results in the observed large line broa- dening (which indicates a distribution of hyperfine fields) and in a slight
