چکیده
The results of ESR measurements on a single crystal of the spin-Peierls compound CuGeO3 doped with 4% Zn are reported. We have observed, for the first time, ESR signals in the antiferromagnetic phase below the Néel temperature(TN = 4.2 K). The excitation energies at zero field are 26.4 and 40.6GHz. The frequency versus magnetic field relation of these ESR signals is well explained by the theory of antiferromagnetic resonance with orthorhombic anisotropy based on the two sublattice model.

Electron Spin Resonance of Ni-doped CuGeO3 in the paramagnetic, spin-Peierls and antiferromagnetic states: Comparison with non-magnetic impurities
We have performed Electron Spin Resonance measurements on single crystals of the doped spin-Peierls compounds CuGe1−ySiyO3 and Cu1−xMxGeO3 with M = Zn, Mg, Ni (x, y ≤ 0.1). The first part of our experiments was performed in the paramagnetic and spin-Peierls phases at 9.5, 95 and 190 GHz. All non-magnetic impurities (Si, Zn and Mg) were found to hardly affect the position and linewidth of the si...
متن کاملRapid suppression of the spin gap in Zn-doped CuGeO3 and SrCu2O3.
The influence of nonmagnetic impurities on the spectrum and dynamical spin structure factor of a model for CuGeO3 is studied. A simple extension to Zn-doped Sr Cu2 O3 is also discussed. Using exact diagonalization techniques and intuitive arguments we show that Zn doping introduces states in the spin-Peierls gap of CuGeO3. This effect can be understood easily in the large dimerization limit whe...
متن کاملEffect of structural distortions on the magnetism of doped spin - Peierls
The chemical selectivity and great sensitivity of the Extended X-ray Absorption Spectroscopy technique allowed the determination, in the paramagnetic phase, of the structural distortions induced by doping in the spin-Peierls CuGeO3 compound. The distorted environments were analyzed as a function of concentration, magnetic nature of impurity and the substitution site (Ni, Mn and Zn impurities on...

متن کاملField-controlled phase separation at the impurity-induced magnetic ordering in the spin-Peierls Magnet CuGeO3.
The paramagnetic fraction surviving at the impurity-induced antiferromagnetic phase transition in the spin-Peierls magnet CuGeO3 is found to increase with an external magnetic field. This effect is explained by the competition of the Zeeman interaction and of the exchange interaction of local antiferromagnetic clusters formed on the spin-gap background near impurities.
