Abstract
In the present communication, we report a strong ferrimagnetic behavior of self-assembled Co[subscript 3]O[subscript 4] nano-platelets, which most likely originates from the intrinsic spin structure of the unique Co[subscript 3]O[subscript 4] structure. The microsphere-like structures are composed of nano-platelets that are entangled together to form the organized network. These anomalous ferrimagnetic properties can be rationalized by supposing that one of the Co[superscript 3+] and one of the Co[superscript 2+] ions are switched between the octahedral and tetrahedral sites. The powder sample was also characterized by x-ray diffraction and superconducting quantum interface device magnetometry.
