NMR relaxation rate of a quantum spin chain with an impurity
The relaxation rate of the nuclear magnetic resonance is calculated exactly for a model spin-1/2 chain with the magnetic impurity. It is shown that the deviations of the impurity's coupling to the chain and the effective impurity's g-factor from the values of the host chain yield special...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The relaxation rate of the nuclear magnetic resonance is calculated exactly for a model spin-1/2 chain with
the magnetic impurity. It is shown that the deviations of the impurity's coupling to the chain and the effective
impurity's g-factor from the values of the host chain yield special features in the temperature and magnetic field
behavior for the relaxation rate.
