A magnetic field transducer includes a tunnel magnetoresistance (TMR) sensing arrangement. The TMR sensing arrangement includes a TMR Wheatstone bridge and a power supply. The TMR Wheatstone bridge includes a plurality of TMR sensing branches, and at least one TMR sensing branch includes a plurality of magnetic tunnel junction (MTJ) elements. The MTJ elements are coupled via conducting elements. The MTJ elements include a plurality of first MTJ elements having a first shape and a plurality of second MTJ elements having a second shape. The first MTJ elements are configured to exhibit controlled vortex states with counterclockwise or clockwise chirality, and the second MTJ elements are configured to exhibit controlled vortex states with counterclockwise or clockwise chirality. The first MTJ elements and the second MTJ elements have opposite remanences with respect to each other.
