“…8 However, a typical crossed-junction PHE sensor has low field sensitivity. Thus, there has been extensive research to increase sensitivity by optimizing sensor materials (i.e., exchange bias bilayer thin films, [9][10][11][12] spin valve thin films, 13,14 trilayer thin films, 15 and shape-induced anisotropy of a single ferromagnetic layer in an elliptically shaped element 16,17 ) and sensor architectures (i.e., tilted cross junction, 18 ring type, 19,20 and Wheatstone bridge type 21 ).…”
