Nematic spin correlations of strain-free detwinned BaFe1.97Ni0.03As2

Recently, we have reported anisotropic spin excitation spectra between at Q1=(pi,0) and Q2=(0,pi) in the tetragonal-phase of detwinned parent and Ni-doped Ba122 system [X. Lu et...近期，我们已有相关报道：在去孪晶母相体系与镍掺杂Ba122体系的四方相（tetragonal-phase）中，Q1=(π,0)与Q2=(0,π)之间的自旋激发谱呈现各向异性[X. Lu等……]
