Polymer-derived SiCN composites with magnetic properties

November 1, 2003
Author(s)
Atanu Saha, Sandeep R. Shah, Rishi Raj, Stephen E. Russek
… Composites consisting of particles of α-iron dispersed in silicon carbonitride (SiCN) were fabricated by a polymer route. The composites had iron inclusions with the same magnetization as bulk iron, but they resisted oxidation up to 500°C and had a …
