magnetic properties.

ABSTRACT
At first both structural and magnetic properties of the MBE deposedFePd
alloy will be presented. Then the experimental technique usedfor the magnetic
domains study will be described, The resultscollected will be presented for
each sample under exam, i.e. anomogeneous thin film and 4 trilayers whose
layers are characterizedby different anistropies.
The results obtained are direct measures of the paramentersdescribing the
domains and can be compared with theoretical models.In particular some of
them allowed us to infer how the exchangevaries with the temperature in a
400C range, up to 50C to the Curiepoint.
