Abstract

We have compared the magnetoresistance of organic spin-valve (SV) structures with regioregular and regiorandom poly (3-hexylthiophene) (RR-P3HT and RRa-P3HT), hole transporting polymers, as the spacer layers sandwiched between two ferromagnetic electrodes. A SV structure of Fe[sub50]Co[sub50]/RRa-P3HT/Ni[sub81] Fe[sub19] was the test structure used. At room temperature, we observed the co-occurrence of two magnetoresistance effects, the spin magnetoresistance and magnetoresistance in the electrodes. [ABSTRACT FROM AUTHOR]
