Investigation of High-Pressure Phase of the Frustrated Antiferromagnet CuFeO₂ by Using Polarized and Unpolarized Neutron Diffraction Experiments with Hybrid-Anvil-Cell

Abstract

In this article, recent advances on polarized and unpolarized neutron diffraction under high pressure condition for frustrated antiferromagnet CuFeO₂ were reviewed. I provide two examples including (i) spherical neutron polarimetry analysis experiment under high pressure, and (ii) unpolarized neutron diffraction experiment in the multi-extreme conditions, high pressure, high field and low temperature. It is hoped that these techniques will help the elucidation of novel pressure-induced physical phenomena related to complex magnetic orderings.
