Magnetoresistive sandwich including sensor electrically parallel with electrical shunt and magnetic biasing layers |
摘要 |
A magnetoresistive permalloy film is deposited upon a substrate and coated with a separating layer composed of titanium or a similar high resistivity, conductive material. A soft biasing layer of a material such as permalloy or a hard biasing material such as cobalt chromium is deposited upon the separating layer to complete a sandwich. All layers are coextensive in outline because their outlines are formed by a single etching step.
