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.
