Description Composites of La0.67Ca0.33MnO3 (LCMO), a colossal magnetoresistance perovskite and NiFe2O4 (NF), an insulating magnetic oxide have been prepared in situ using microwave-refluxing technique. Microstructural studies of the composites show that the two phases are uniformly distributed and the grain size of both the phases is identical, in the range 10–40 nm. The NF appears as a separate phase for concentrations x > 0.10 M, where M is the molecular weight of NF in the starting precursor solution. For concentrations
