PURPOSE:To obtain the element suitable for a magnetoresistance effect head which offers a high output voltage and a proper bias magnetic field without a division of the output for the magnetic field by forming a Mo film on a Permalloy film formed on a substrate. CONSTITUTION:On the substrate 5 consisting of glass, firstly e.g. a Permalloy film 6 of 350Angstrom thick and next e.g. a Mo film 7 of 2,000Angstrom thick are vapor-deposited by electron beam, after which a conductor 8 is formed. The output voltage-signal magnetic field curve of this element almost does not show a division of the output for the magnetic field and the output voltage is high and a proper bias magnetic field is applied. The intensity of this bias magnetic field increases as a detection current increases. Accordingly, the proper intensity of the bias magnetic field can be obtained by flowing a proper detection current. |
