Size and morphology effects on the high pressure behaviors of Mn₃O₄ nanorods.

ABSTRACT: The high-pressure behaviors of Mn₃O₄ nanorods were studied by high pressure powder synchrotron X-ray diffraction and Raman spectroscopy. We found that the initial hausmannite phase transforms into the orthorhombic CaTi₂O₄-type structure, and then to the marokite-like phase upon compression. Upon decompression, the marokite-like phase is retained at the ambient pressure. Compared with Mn₃O₄ bulk and nanoparticles, Mn₃O₄ nanorods show obviously different phase transition behaviors. Upon compression, the phase transition sequence of Mn₃O₄ nanorods is similar with the nanoparticles, while the decompression behavior is consistent with the bulk counterparts. The hausmannite phase shows h
