TL;DR
This study uses 29Si NMR to investigate how pressure affects the electronic and magnetic properties of URu2Si2, revealing persistent density of states suppression and changes in magnetic susceptibility.
Contribution
It provides new insights into the pressure dependence of the hidden order phase in URu2Si2 through detailed NMR measurements.
Findings
Knight shift decreases with pressure
Density of states suppression persists under pressure
Onset temperature of suppression is mildly enhanced
Abstract
We report 29Si nuclear magnetic resonance measurements of single crystals and aligned powders of URu2Si2 under pressure in the hidden order and paramagnetic phases. We find that the Knight shift decreases with applied pressure, consistent with previous measurements of the static magnetic susceptibility. Previous measurements of the spin lattice relaxation time revealed a partial suppression of the density of states below 30 K. This suppression persists under pressure, and the onset temperature is mildly enhanced.
