A reconstruction from small-angle neutron scattering measurements of the real space magnetic field distribution in the mixed state of Sr${}_2$RuO${}_4$

Abstract

We have measured the diffracted neutron scattering intensities from the square magnetic flux lattice in the perovskite superconductor Sr${}_2$RuO${}_4$, which is thought to exhibit p-wave pairing with a two-component order parameter. The relative intensities of different Bragg reflections over a wide range of field and temperature have been shown to be inconsistent with a single component Ginzburg-Landau theory but qualitatively agree with a two component p-wave Ginzburg-Landau theory.
