Electronic Phase Separation induced dramatic enhancement of large magnetoresistance in Organic Spin Valves
ORAL
Abstract
Organic spin valves (OSVs) have been studied widely with respect to the long spin relaxation time of the carriers in the organic materials and their synthetic versatility, ease of manufacturing and pliability. Recent advances focused on the spinterface and the multi-functionalities of OSVs. Here we employ LPCMO with high spin polarization and electronic phase separation (EPS) to tune the MR of the OSV, which depends strongly on the pre-set magnetic field, voltage and temperature due to the spin-flip scattering in LPCMO and the interface. An extremely high MR of 438% and the rangeability of 5.9 times are observed. Our findings point an alternative way for multistate of OSVs and controllable room temperature OSVs by using LPCMO with high Tc and electronic phase separation.
