n-type indium-Au van der Pauw (vdP) shape hybrid macro-structure were successfully fabricated by flash evaporation technique. The elemental composition of the prepared films was confirmed by energy dispersive X-ray spectroscopy microanalysis (EDX). The morphologies and crystal structures of the films were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. The magnetoresistance of the prepared hybrid structure was measured at room temperature and 100mA current ans a variable magnetic filed (0-8kG). The effect of sensor geometry on magnetoresistance was studied.
