Large Magnetoresistance in Magnetically Coupled SrRuO3 –CoFe2O4 Self-Assembled Nanostructures

A new way to induce a large magnetoresistance has been achieved by self-assembled nanostructures consisting of ferromagnetic spinel CoFe2O4 (CFO) and metallic perovskite SrRuO3 (SRO). The interdiffused Fe3+ ions in SRO have paved the way to strong magnetic couplings with CFO nanopillars, resulting in the suppression of spin-polarized electron scattering.
