## Title

- title: Tunnel magnetoresistive sensors with non-hysteretic resistance-magnetic field
    curves using noncollinear interlayer exchange coupling through RuFe spacers
  title_type: original
  lang: en

## Description

- description: Magnetic stabilization of the ferromagnetic layers of magnetoresistive
    elements is a key technological requirement for highly sensitive and accurate
    magnetic sensors. Here, we report on a tunnel magnetoresistive (TMR) sensor wherein
    the free layer (FL) magnetization is stabilized by combining exchange bias, noncollinear
    interlayer exchange coupling through a RuFe spacer, and orange-peel ferromagnetic
    coupling. This method facilitates the stabilization of the FL magnetization over
    a wide range of noncollinear angles with respect to the pinning direction by controlling
    the composition of the RuFe spacer. Moreover, the uniaxial anisotropy induced
    in the FL by annealing plays an important role in the resistance–magnetic field
    (R–H) curve, which was studied both experimentally and through simulation. The
    TMR devices exhibited negligible hysteresis even in the major R–H loops, which
    is promising for magnetic field-sensing applications.
