Abstract
Domain structures in RCo5 compounds were observed with Kerr effect in fields up to 8000 Oe. The domain structures in SmCo5 are much coarser than in the other compounds. It is shown that this difference may be due to a higher wall energy in SmCo5. The idea is developed that this higher wall energy is responsible for the higher coercivities of SmCo5.This publication has 14 references indexed in Scilit:
