Broad Linewidth of Antiferromagnetic Spin Wave due to Electron Correlation

We study magnetic excitations in a bilayer of an antiferromagnetic (AF) insulator and a correlated metal, in which double occupancy is forbidden. The effective action of the AF spin wave in the AF insulator is derived by using the path integral formula within the second order of interplane coupling....
