Absence of long range order in the frustrated magnet SrDyO due to trapped defects from a dimensionality crossover
N. Gauthier, A. Fennell, B. Prévost +12
Magnetic frustration and low dimensionality can prevent long range magnetic order and lead to exotic correlated ground states. SrDyO consists of magnetic Dy ions for…
Doping Dependence of Collective Spin and Orbital Excitations in Spin 1 Quantum Antiferromagnet LaSrNiO Observed by X-rays
G. Fabbris, D. Meyers, L. Xu +14
We report the first empirical demonstration that resonant inelastic x-ray scattering (RIXS) is sensitive to \emph{collective} magnetic excitations in systems by probing the N…
Anisotropy of the antiferromagnetic spin correlations in the superconducting state of YBa_2Cu_3O_7 and YBa_2Cu_4O_8
A. Uldry, M. Mali, J. Roos +1
We present evidence that the antiferromagnetic spin correlations in optimally doped YBa_2Cu_3O_7 and underdoped YBa_2Cu_4O_8 develop a surprisingly strong anisotropy in the superco…
Analysis of NMR Spin-Lattice Relaxation Rates in Cuprates
A. Uldry, P. F. Meier
We investigate nuclear spin-lattice relaxation data in the normal state of optimally doped YBaCuO_7 by analyzing the contributions to the relaxation rate of the copper, planar oxyg…
