Objective: To study the dynamics of magneto-resistance in organic diodes
Approach: Measure electronic transport and magneto-transport of organic diodes as a function of frequency with an applied magnetic field using admittance spectroscopy
Preliminary Results & Significance:
The magneto-conductance (inverse of resistance) of a conducting polymer-based diode was measured as a function of frequency and bias voltage. The observed properties show that the relevant underlying processes occur on a timescale of ~100 ns.
