MAGNETORESISTIVE PROPERTIES OF NI-BASED THICK-FILMS

Investigations have been carried out on the electrical properties of nickel-based films prepared from air fireable pates on alumina substrates. In particular, magnetoresistive effects have been studied as a function of temperature, strength and direction of the magnetic field. These properties were detwrmined in films at different stages of formation, i.e. prepared at various peak firing temperatures and dwell times, and compared with those displayed by nickel folis. These results provide the basis for the development of magnetoresistive thick-film sensors
