Spinterface-Induced Modification in Magnetic Properties in Co₄₀Fe₄₀B₂₀/Fullerene Bilayers

Organic semiconductor/ferromagnetic bilayer thin films can exhibit novel properties due to the formation of spinterface at interface. Buckminsterfullerene (C60) has been shown ferromagnetism interface when it is placed next a ferromagnet (FM) such as Fe or Co. Formation occurs orbital hybridization and spin-polarized charge transfer In this work, we have demonstrated that one enhance magnetic anisotropy low Gilbert damping alloy CoFeB film by introducing C60 layer. We increases increasing thickness C60, which might be result spinterface. However, domain structure remains same in samples compared reference film.
