Effect of Pressure on Magnetic Structure in Heavy Fermion CeRhIn5
Abstract
The effect of hydrostatic pressure on the in-commensurate 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) micro-B per Ce at 1.6 K, which is the same as the ambient-pressure value. The Neel temperature TN = 3.8(1) K is also the same as the ambient-pressure one, although the curve of order parameter has changed by pressure. The incommensurability delta of the magnetic wave vector qM = (1/2,1/2, delta) has reduced from delta = 0.297 at ambient pressure to delta = 0.294(1) at 3.8 kbar.
