A study of interface-sustained ferromagnetism in 1/2(1−x)Ln2O3-xSrO/1/3Co3O4 nano-composite

HR-TEM image depicts the heterogeneous tri-oxide comprising respective oxide domains in nano-scale, 1/2(1−x)Ln2O3-xSrO/1/3Co3O4. The delicate mixing triggers the interfacial induction effect leading to magnetic properties at room temperature, as shown by its hysteresis loop.
