Spin waves and magnetic interactions in LiCu2O2
T. Masuda, A. Zheludev, B. Roessli +2
The quasi-one-dimensional helimagnet LiCu2O2 was studied by single crystal inelastic neutron scattering. The dispersion relation of spin wave excitations was measured in the vicini…
Half-ordered state in the anisotropic Haldane-gap antiferromagnet NDMAP
A. Zheludev, B. Grenier, E. Ressouche +2
Neutron diffraction experiments performed on the Haldane gap material NDMAP in high magnetic fields applied at an angle to the principal anisotropy axes reveal two consecutive fiel…
Cooperative ordering of gapped and gapless spin networks in CuFeGeO
T. Masuda, A. Zheludev, B. Grenier +4
The unusual magnetic properties of a novel low-dimensional quantum ferrimagnet CuFeGeO are studied using bulk methods, neutron diffraction and inelastic neutron…
Erratum: Dynamics and scaling in a quantum spin chain material with bond randomness
T. Masuda, A. Zheludev, K. Uchinokura +2
Follow-up neutron measurements, performed on a sample much larger than the one used in the original study, show that in the energy range 0.5-45 meV the magnetic excitations in BaCu…
Anomalous percolation and quantum criticality in diluted rare-earth nickelates
J. V. Alvarez, H. Rieger, A. Zheludev
A microscopic model for the diluted spin-mixed compounds (R_xY_(1-x))_2BaNiO_5 (R=magnetic rare-earth) is studied using Quantum Monte Carlo (QMC). The ordering temperature is shown…
