                      studies of hausmannite up to 7.2 GPa and 1273 K. The Mn3O4
                      tetragonal spinel is found to transform to a $9.6\%$ denser
                      polymorph of the CaMn2O4-type structure at 7.2 GPa and 673
                      K, under milder conditions than those of any transformations
                      to postspinel phase described so far. Upon heating at high
                      pressure, the Mn3O4 phase undergoes decomposition and
                      finally disappears in favor of MnO at temperatures above
                      1073 K. A fit of the pressure dependence of the volume of
                      tetragonal phase to the Birch−Murnaghan equation of state
                      yields the bulk modulus, K0, of 132.6 ± 3.1 GPa if the
                      first pressure derivative of the bulk modulus is fixed to 4,
                      and K0, of 102 ± 10 GPa for K0′ refined to 18.1 ± 5.6.
                      Nonlinear compression behavior is observed for both
                      crystallographic axes, with the c axis being more
                      compressible than the a axis. Axial ratios in CaMn2O4-type
                      Mn3O4 with temperature are also estimated. Surprisingly, the
                      lattice distortion of the marokite-like phase is not
                      preserved upon releasing pressure and temperature to ambient
                      conditions},
