Observation of superficial antiferromagnetism in Co3O4 polycrystals
Observation of superficial antiferromagnetism in Co3O4 polycrystals Abstract: We report on a systematic study about the magnetic properties of Co3O4 polycrystals with large size distribution (100-1200 nm) and the crystallite size of 68(4) nm on average. […]
