Abstract
The magnetic behavior of Co and Fe granular films was studied relative to their host matrix environment (BN, SiO2). The crystal structure of Co and Fe in the as-deposited samples is alpha-Co (hcp) and alpha-Fe (bcc) respectively, with particle sizes ranging between 3 and 9 nm. Th e coercivities measured ranged from a few tens to a few hundreds Oe, w ith the higher values observed for particles embedded in the oxygen ba sed matrix.
