Objective:
A precise absolute magnetometer based on organic spintronics that is scalable to micron dimensions, has low cost and that is not adversely affected by environmental influences (temperature, air etc.).
Approach: Integrated bipolar MEH-PPV device above magnetic field strip lines for magnetic resonant excitation. The B-field is measured through spin-dependent current changes under magnetic resonance.
Results and Significance: For the p-conjugated polymer MEH-PPV, an ABSOLUTE sensitivity of
