Claims20
An article comprising:
- at least one fiber that includes a fiber core;
- and
- an interface layer that extends around the fiber core, and the interface layer includes a first ceramic matrix and ferromagnetic regions dispersed through the first ceramic matrix.
A method of fabricating an article, the method comprising:
- forming an interface layer around a fiber core of at least one fiber, the interface layer includes a first ceramic matrix and ferromagnetic regions dispersed through the ceramic matrix.
A magnetic article comprising:
- a ceramic matrix;
- and
- a plurality of filler structures dispersed through the ceramic matrix, at least one of the filler structures includes a substrate, a ferromagnetic layer around the substrate, and a ceramic barrier layer that encloses the ferromagnetic layer.
