Abstract

We report observation of spin-pair excitations in Ba2YCu3O6, with in the range 0.0-0.9. The frequency of the excitations, and hence the value of the exchange constant, J=950 cm-1, is similar to that reported recently for (nonsuperconducting) La2CuO4. The present observation of magnetic excitations in a superconducting material, and of their evolution as a function of, demonstrate a large influence of carrier concentration on the spin-fluctuation dynamics.
