摘要： A magnetoresistive element (2) comprising a reference layer (23), a ferromagnetic sense layer (21) having a free sense magnetization (210), and a tunnel barrier layer (22) between the reference layer (23) and the sense layer (21). The sense layer (21) comprises a first sense layer portion (211) in contact with the tunnel barrier layer (22) and a second sense layer portion (212) in contact with the first sense layer portion (211). The first sense layer portion (211) is configured such that a magnetic coupling between the first and second sense layer portions (211, 212) is between ±10 -4 J/m 2 and ±10 -3 J/m 2 ; and a perpendicular magnetic anisotropy (PMA) originating from the interface between the first sense layer portion (211) and the tunnel barrier layer (22) is between 8x10 4 A/m and 8x10 5 A/m, such as to shift positively the TCS of the magnetoresistive element (2) and compensate the negative temperature coefficient of TMR of the magnetoresistive element (2).
