We present a NQR and Zeeman perturbed NQR investigation of a KCuF3 single crystal across T-N, looking for evidence of a local rearrangement of the Cu unoccupied orbitals. Although no change is detected in the NQR coupling, we confirm a gradual growth of the magnetic volume fraction for T/T-N greater than or equal to 0.87 previously detected by muSR.

Abstract
We present a NQR and Zeeman perturbed NQR investigation of a KCuF3 single crystal across T-N, looking for evidence of a local rearrangement of the Cu unoccupied orbitals. Although no change is detected in the NQR coupling, we confirm a gradual growth of the magnetic volume fraction for T/T-N greater than or equal to 0.87 previously detected by muSR.File in questo prodotto:
