We investigated the electric field gradient tensor at the Cu nuclei by Zeeman perturbed nuclear quadrupole resonance in orbitally ordered KCuF3. Our data show the presence of two inequivalent crystallographic sites with distinct orientations of the copper wave function. compatibly with the proposed orbital order for this compound, An unusual behaviour of the paramagnetic NQR signal at the Neel transition is reported.

Abstract
We investigated the electric field gradient tensor at the Cu nuclei by Zeeman perturbed nuclear quadrupole resonance in orbitally ordered KCuF3. Our data show the presence of two inequivalent crystallographic sites with distinct orientations of the copper wave function. compatibly with the proposed orbital order for this compound, An unusual behaviour of the paramagnetic NQR signal at the Neel transition is reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
