Abstract The Y1−x Pr x Ba2Cu3O6.9 system has been investigated by quantitativeμ-Raman measurements. The magnetic response of the antiferromagnetic ordered Cu spins in the CuO2 plane has been observed via the two-magnon-Raman scattering. The in-plane exchange energy is determined to 780 cm−1 in the system withx=1. Phonon behavior as well as magnetic scattering indicate that the band structure of the CuO2 planes in PrBa2Cu3O6.9 is similar to that in insulating YBa2Cu3O6.
