Abstract

The coercivity of epitaxial magnetic garnet films has been measured on both stripe and bubble domain structures by the domain wall oscillation method. The bubble coercivity versus bubble array density relation has been determined experimentally. It was found that on the array reaching a certain density the apparent coercivity was strongly influenced by the neighbouring domains interaction. Also, the coercivity of bubbles was found to be a function of domain wall structure (domain wall energy); the presence of Bloch lines increased the experimentally measured coercivity value.
