Critical spin dynamics of the 2D quantum Heisenberg antiferromagnets: Sr_2CuO_2Cl_2 and Sr_2Cu_3O_4Cl_2
Y. J. Kim, R. J. Birgeneau, F. C. Chou +2
We report a neutron scattering study of the long-wavelength dynamic spin correlations in the model two-dimensional square lattice Heisenberg antiferromagnets SrCuOC…
Neutron Scattering study of Sr_2Cu_3O_4Cl_2
Y. J. Kim, R. J. Birgeneau, F. C. Chou +10
We report a neutron scattering study on the tetragonal compound Sr_2Cu_3O_4Cl_2, which has two-dimensional (2D) interpenetrating Cu_I and Cu_{II} subsystems, each forming a S=1/2 s…
Magnetic properties of the S=1/2 quasi-one-dimensional antiferromagnet CaCu2O3
V. Kiryukhin, Y. J. Kim, K. J. Thomas +5
We report single crystal growth and magnetic susceptibility and neutron diffraction studies of the S=1/2 quasi-1D antiferromagnet CaCu2O3. The structure of this material is similar…
Direct Observation of the Quantum Energy Gap in S = 1/2 Tetragonal Cuprate Antiferromagnets
K. Katsumata, M. Hagiwara, Z. Honda +9
Using an electron spin resonance spectrometer covering a wide range of frequency and magnetic field, we have measured the low energy excitations of the S=1/2 tetragonal antiferroma…
X-ray scattering study of two length scales in the critical fluctuations of CuGeO3
Y. J. Wang, Y. -J. Kim, R. J. Christianson +3
The critical fluctuations of CuGeO have been measured by synchrotron x-ray scattering, and two length scales are clearly observed. The ratio between the two length scales is fo…
