- Abstract
- A correlation between composition, microstructure, and magnetic properties of sputter-deposited CoFeSiB alloy films has been studied Various analytical tools and micromagmetic models were employed to understand the details of microstructural evolution and magnetic reversal processes, respectively The CoFeSiB alloy film shows significantly different microstructure and magnetic properties depend on the Co concentration When the Co concentration is below 75 at %, the alloy has an amorphous phase exhibiting magnetic softness with negative remanence Meanwhile, beyond 75 at %, the structure consists of nanocrystals precipitated in the amorphous matrix, which becomes magnetically hard with positive remanence as well as antiferromagnefic exchange coupling (C) 2010 Acta Materialia Inc Published by Elsevier Ltd All rights reserved
