Figure 5From: Modification of crystal anisotropy and enhancement of magnetic moment of Co-doped SnO2 thin films annealed under magnetic fieldZFC-FC performed on sample PP. Typical ZFC-FC curves observed on DMO system, and the peak at 41 to 47 K is attributed to a minority Co3O4 AFM nanoclusters. In the inset, an extrapolation of the 1/X curve intercepts the temperature axis at a negative value demonstrating that a part of Co atoms is AFM coupled.Back to article page
