Magnetic diffraction studies under very high pressures

Abstract

In 1992, a joint project for studying magnetic materials at very high pressures by neutron diffraction was established between the Laboratoire Léon Brillouin (LLB), Saclay, and the Kurchatov Institute, Moscow. Crystal structure studies under pressures in excess of 10 GPa had already been made in Moscow since the early 198Os, and the Russian team had developed considerable experience in using sapphire or diamond anvils for neutron measurements with sample volumes of less than one cubic millimeter. It thus looked promising to combine this expertise with the powerful neutron facilities available at the LLB.
