Abstract

A magnetic field sensor includes first and second sensors for detecting first and second magnetic components according to first and second directions. Each sensor includes a flux concentrator including first and second magnetic parts, an air gap between the parts, and a magnetoresistive element in the air gap. Each magnetoresistive element includes a reference layer having a fixed magnetization direction, the fixed magnetization direction of the first and second sensors being substantially identical, and a sensitive layer having a variable magnetization direction, the variable magnetization direction of the first sensor when the first sensor is in a state of rest being substantially identical to the variable magnetization direction of the second sensor when the second sensor is in the state of rest. The air gaps of first and second sensor are oriented parallel to a direction XY which is, at ±15°, the bisector of the first and second directions.
