Structural Parameters Related to the Magnetic Phases in Fe<sub>2</sub>Mo<sub>3</sub>O<sub>8</sub>

Abstract
A systematic structural study of the Fe2Mo3O8 altermagnet system as a function of pressure, temperature, and magnetic field has been conducted. The well-known magnetic field-induced first-order transition is found to be isostructural. The magnetostructural response (Dc/c) for a magnetic field transverse to the displacement is determined. Hydrostatic pressure-dependent measurements reveal a significantly larger compression response in the c-axis direction relative to the ab plane. The structural measurements are mapped onto measurements under doping. Pressure is seen as a clean way to tune the properties of this class of materials. NSF grant DMR-2313456 supports this work
