FIG. 1.

(Color online) Inverse spinel structure showing the location of constituents, namely, Fe3+ and Co2+/Fe3+ at tetrahedral (p) and octahedral (q) sites.

FIG. 2.

(Color online) Experimental magnetic Compton profile (MCP) of CoFe2O4 at 8 and 300 K and fixed 2.5 T. Also shown here is the fitted (solid line) profile along with the contributions of the constituent profiles. Experimental error in the MCP of CFO is within the size of the symbol used.

Image of FIG. 3.
FIG. 3.

(Color online) Temperature-dependent magnetization (M–T) for the Co-ferrite measured at a field of 2.5 T along with spin moments at few data points deduced from MCS. The lines through MCP data points are drawn to guide the eyes only. In the inset, variation in total magnetization (M–H data from VSM) and also the spin moment (MCP data) with external magnetic field (at 8 K) are depicted. It is noteworthy that in the inset, the total spin moment in MCP data is calculated using the flipping ratio (R) with low statistics (one cycle consisting of four times reversal of field). The errors in MCP data at 8 and 300 K (12–15 cycles) are within the size of the symbols used.

Table I.

Temperature-dependent magnetic moments by the line shape analysis of MCPs of cobalt ferrite. The magnetization (M–T) data measured using the VSM is also included. The error involved in the MCP and its components is within ±0.03 μB/f.u.
