摘要：

The effect of hydrostatic pressure on the incommensurate antiferromagnetic structure of CeRhIn5 is investigated with neutron diffraction using a He pressure cell. At 3.8 kbar, the staggered magnetic moment is 0.37(4) μB per Ce ion at 1.6 K, which is the same as the ambient-pressure value. The Néel temperature TN=3.8(1) K is also the same as the ambient-pressure one, although the curve of the order parameter has changed with pressure. The incommensurability δ of the magnetic wave vector qM=(1/2,1/2,δ) has reduced from δ=0.297 at ambient pressure to δ=0.294(1) at 3.8 kbar.
