Large magnetoresistance in magnetically coupled SrRuO₃ -CoFe₂O₄ self-assembled nanostructures

Adv Mater. 2013 Sep 14;25(34):4753-9. doi: 10.1002/adma.201301461. Epub 2013 Jul 12.


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.

Keywords: cobalt ferrite (CoFe2O4); magnetoresistance; self-assembled nanostructures; strontium ruthenate (SrRuO3).
