Abstract
▶ Applications of magnetic sensors often require high frequency operation. ▶ We examine the frequency response of organic magnetoresistive sensors. ▶ We demonstrate that operation up to 100
kHz is possible high current. ▶ High current densities are advantageous, frequency response is limited by carriers with low mobility.
Organic magnetoresistive (OMAR) devices show a large enough magnetoresistive response (typically 10%) for potential applications as magnetic field sensors. However, applications often require sensing high frequency magnetic fields, and the examination of the frequency-dependent magnetoresistive response is therefore required. Analysis of time constants that limit the frequency response may also shed light on the mechanism behind the OMAR effect.
