Fig. 4: Average magnetic moment per magnetic atom 〈M〉 and Curie temperature TC for La(Fe0.75D0.25)O3 and La(Fe0.875D0.125)O3.

a Average magnetic moment per magnetic atom 〈M〉 and b Curie temperature TC for La(Fe0.75D0.25)O3. c 〈M〉 and d TC for La(Fe0.875D0.125)O3. The impurity D is taken as 3d and 4d transition metal elements. For comparison, the TN = 650 K of host LaFeO3 is also included in (b) and (d). Results here are obtained without Fe substrate.
