Geophysically relevant pressures offer a mechanism to create and probe new phases. Here, two separate areas connected by high pressure will be presented. The first is the chemical synthesis of new binary compounds at high pressure, exploiting the unusual transparency of diamond to probe reactions in situ and elucidate their formation conditions. In this area we are interested in harnessing the orbital angular momentum of heavy elements such as bismuth towards a host of physical properties. Specifically, we synthesized new superconducting binaries compounds including CuBi and Cu11Bi7. We also synthesized the first iron-bismuth binary compound featuring the first iron-bismuth bond in the solid state. In an orthogonal direction, we are manipulating existing materials with high pressure to create new physical properties. Recent studies on jarosite will be presented and the implications for spin liquids will be discussed.
