Observation of magnetic order in a superconducting YBa2Cu3O6.6
Description
Polarized beam neutron-scattering measurements on a highly perfect crystal of YBa2Cu3O6.6 show a distinct magnetic transition to a different phase with an onset at about 235 K, the temperature expected for the pseudogap transition. The moment is found to be about 0.1(micro)B for each sublattice and has a correlation length of at least 75 (angstrom). We found the critical exponent for the magnetic neutron intensity to be 2=0.37 ± 0.12. This is the proper range for the class of transition that has no specific-heat divergence possibly explaining why none is found at the pseudogap transition
