Abstract

We have developed a new scattering geometry for magnetic neutron scattering experiments on YBa₂Cu₃O₇ in which the phonon background around q ~ ( π a, π a), ω ~ 40meV is significantly reduced. We use this new approach to study the previously detected sharp magnetic excitation at ~ 40meV in the superconducting state in detail. The excitation does not shift substantially in energy up to at least 75K. (~0.8T_c). Polarized neutron scattering experiments (horizontal minus vertical field) confirm the magnetic origin of the 40meV excitation and put stringent limits on the magnetic scattering intensity in the normal state.
