Development of Hybrid-Anvil-Cell for Polarized and Unpolarized Neutron Diffraction Study

Abstract

We developed a hybrid anvil high-pressure cell (HAC) for neutron diffraction experiments with multi-extreme conditions, including high pressure, a high magnetic field, and low temperature, and for spherical neutron polarimetry analysis under pressure. By using the HAC, we successfully conducted neutron diffraction experiments under high-pressure (5.0 GPa) and high-magnetic-field (8 T) conditions, and conducted spherical neutron polarimetry analysis at up to 4.0 GPa. This review introduces the technical development of the HAC and recent experimental results for multiferroic materials.
