Abstract
EPR measurements at microwave and far-infrared frequencies on Gd-spins in powders of Bi2Sr2Ca1-xGdxCu2O8+y and GdBa2Cu3O7-d reveal a marked increase in linewidth at low temperatures. This cannot be fully accounted for in terms of crystal field split ting, dipolar broadening and inhomogeneous demagnetization. It is argued that a large contribution can come from interactions of the Gd-spins with antiferromagnetic excitations in the CuO-planes.
