Crystalline Order Effects on the Magnetic Properties of Superlattices made of Cobalt Nanocrystals

Abstract : We present the magnetic property evolution in long-range ordered fcc supracrystals of Co nanocrystals (NCs) induced mainly by nanocrystallinity. By increasing the nanocrystalline order of individual NCs, ac susceptibility measurements indicate a significant increase in the 'interaction-to-anisotropy' energy ratio, a trend favourable for the formation of SFM state in these 3D supracrystals.
