Abstract

Neutron scattering experiments have been carried out for a heavy fermion superconductor URu₂Si₂. We found that the (1 0 0) magnetic Bragg peak intensity is reduced by 1--2 superconducting transition temperature of 1.15, K. This is direct evidence of the interplay between magnetism and superconductivity in URu₂Si₂.
