Hooge parameter (circles) and magnetoresistance-sensitivity-product (solid line) versus magnetic field at each angle are shown in panels (a)–(e). H free denotes the peak position of MSP in negative field region. Our focused regions are shown by green circles. α mag versus magnetic field of each angle is plotted in panel (f). The measurement is carried out at room temperature.
