Observation of two low-energy responses in UPd(2)Al(3): Interaction of magnetism and superconductivity?
Neutron inelastic scattering measurements have been performed for the heavy fermion superconductor UPd(2)Al(3). From comparison of the results with calculation, it is suggested that the spin fluctuation determines the superconducting transition temperature T(c), and that the strong coupling between the heavy electrons and spin waves may lead to the observation of two low-energy responses. It is also suggested that within the model investigated, the spin wave excitation energy may be reduced below T(c).
