Abstract

The authors have investigated magnetic domain wall induced capacitance variation as a tool for the detection of magnetic reversal in magnetic nanowires for in-plane (NiFe) and out-of-plane (Co/Pd) magnetization configurations. The switching fields in the capacitance measurements match with that of the magnetoresistance measurements in the opposite sense. The origin of the magnetocapacitance has been attributed to magnetoresistance. This magnetocapacitance detection technique can be useful for magnetic domain wall studies.
