During the last few decades, diamond anvil cell (DAC) techniques have become the most successful method of pressure generation for work in the multimegabar pressure range. However, there are still problems related to carrying out in-situ high-temperature experiments. We describe two most common methods of heating in DACs — internal laser heating and external electrical (resistive) heating. The two methods are complimentary and allow temperatures over 3000 K at pressures over 200 GPa. Application of the high-temperature high-pressure methodology is illustrated with studies on structures and phase relations of geophysically important materials — iron oxide Fe3O4 and iron-nickel alloys.
