Abstract:
Magnetoresistive transducer for measuring a magnetic field, the magnetoresistive transducer comprising a magnetoresistive component (1) comprising a multilayer-type magnetoresistive strip (2) bent in accordance with a repeating geometrical pattern (7a, 7b), the pattern having a series of substantially parallel sections (7a, 7b) for reducing demagnetizing fields, the magnetoresistive strip (2) being of a metallic multilayer magnetic structure and formed from a stack (13) of layers (14) of a magnetic metallic material separated by layers (15) of an electrically conductive, non-magnetic metallic material wherein said magnetic metallic layers are coupled by an antiferromagnetic coupling; the magnetoresistive component (1) is supported by a non-conductive substrate (12) and has power points (5,6) connected to the magnetoresistive component (1) by leads (3,4); a width (t) of the sections (7b) of the series is smaller than a length (v) of said sections; and the length (v) of said sections (7b) is .gtoreq.10 .mu.m and the width (t) of said sections is such that 0.2 .mu.m.ltoreq.t.ltoreq.5 .mu.m.
