Here we report the results of laboratory experiments at asthenospheric pressure (about 3 GPa) and on samples previously deformed to high strains (γ ≈ 9). These experiments were designed to investigate ...

Electrical conductivity experiments use four to eight tungsten wires, magnetic susceptibility experiments require a microloop of about ten turns of wire, and high-temperature experiments use eight ...
