Field-induced low energy excitations in the co-doped superconductor (La,Sr)2CuO4+y

DOI

Despite immense research efforts, high temperature superconductivity remains a mystery. We will here study the interplay between magnetism and SC, in the co-doped cuprate La2−xSrxCuO4+delta. We recently found that for x=0.06, there is no static magnetism in zero field, but an applied magnetic field would linearly induce a magnetic signal from incommensurae order. Previous inelastic neutron data shows a 5 meV spin gap in zero field, whereas data in 6 T show a complete absence of a gap. We aim to study the gap region in lower fields in order to elucidate how the gap fills upon application of a field.
