Abstract
Lorentz electron transmission microscopy observations of the domains-structure in amorphous Fe1-xZrx (x = 9 to 13 % ) films (1000 to 2000 Å thick) near liquid helium temperature are reported. Several levels of magnetic fluctuations with a large distribution of wave lengths ranging from several tens of µm to few hundreds angstroms are seen.
