Abstract
Presents a review of the properties and applications of the permalloy magnetoresistive sensors of magnetic fields. Information on the manufacturing and biasing methods is given. The basic parameters-sensitivity, dimensions, linearity, resolution and transducer errors-and methods for improving them are analysed. The examples of permalloy microsensors, miniature sensors and large-area sensors are presented. The application of permalloy magnetoresistors to measuring magnetic fields and constructing electrical and non-electrical transducers is described.Keywords
