Development of High-Pressure Technique for Single-Crystal Magnetic Neutron Diffraction under 10 GPa

Abstract

A new hybrid-type anvil technique for high-pressure single-crystal magnetic neutron diffraction under 10 GPa is described. The hybrid anvil is composed of an opposed pair of two kinds of anvils. One is a large sapphire anvil or a supported SiC anvil and the other is a tungsten carbide (WC) anvil which has a hollow at the center of the culet. In a feasibility test of the hybrid anvil, we could generate pressures of up to 10 GPa at a load of 3.8 tons with high stability.
