Thermodynamics of Non-Uniform Compression in H-Bonded Molecular Solids
Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which... -
High pressure phase transitions in metal-formate perovskites
The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials' magnetic and electric properties, in... -
Phase evolution in the transition from epsilon to gamma glycine
Glycine, the simplest naturally-occurring amino acid, exhibits unusually extensive phase diversity. Three polymorphs are known under ambient conditions. Each shows different... -
Continued studies of the temperature-pressure phase diagram of BiFeO3
Bismuth ferrite is the most widely studied multiferroic material primarily due to the observation of both room temperature magnetic and electric ordering. Despite extensive... -
Structural analysis of Kitaev spin liquid candidate beta-Li2IrO3 under pressure
The theoretical predication of Kitaev spin liquid in honeycomb iridates triggered tremendous interests. We recently discovered a new candidate material, beta-Li2IrO3 with a 3D... -
Structure of a 2D antiferromagnet under pressure
Magnetic superexchange is strongly dependant on the degree of orbital overlap and hence the interatomic distances and angles within a structure. One way of tuning magnetic... -
The role of step-size on the pressure phase diagram of BiFeO3
bismuth ferrite (BFO) remains the most studied multiferroic as a result of room temperature electric and magnetic ordering. However, real world applications are limited due to...
