Query: Thermodynamic Geometry and Phase Transitions of Dyonic Charged AdS Black
  Holes   We investigate phase transitions and critical phenomena of four dimensional
dyonic charged AdS black holes in the framework of thermodynamic geometry. In a
mixed canonical grand canonical ensemble with a fixed electric charge and
varying magnetic charge these black holes exhibit liquid gas like first order
phase transition culminating in a second order critical point similar to the
Van der Waals gas. We show that the thermodynamic scalar curvature R for these
black holes follow our proposed geometrical characterization of the R-crossing
Method for the first order liquid gas like phase transition and exhibits a
divergence at the second order critical point. The pattern of R crossing and
divergence exactly corresponds to those of a Van der Waals gas described by us
in an earlier work.
