Description
The time integrals of the two-time auto and nearest-neighbor spin-pair correlation functions are calculated for the spin 1/2 isotropic Heisenberg magnet with antiferromagnetic exchange integral in the paramagnctic region. They are used to estimate the temperature dependence of the NMR line width of F19 in RbMnF3. The obtained result is in an excellent agreement with the experimental data measured by Hess and Hunt. A conjecture is presented for the temperature dependence of the time integrals of the two-time spin-pair correlation functions at high temperatures.
