Field-induced transition between magnetically disordered and ordered phases in underdoped La(2-x)SrxCuO4
B. Khaykovich, S. Wakimoto, R. J. Birgeneau +5
We report the observation of a magnetic-field-induced transition between magnetically disordered and ordered phases in slightly under-doped La(2-x)SrxCuO4 with x=0.144. Static inco…
Thermodynamic properties of excess-oxygen-doped La2CuO4.11 near a simultaneous transition to superconductivity and long-range magnetic order
G. A. Jorge, M. Jaime, L. Civale +7
We have measured the specific heat and magnetization {\it versus} temperature in a single crystal sample of superconducting LaCuO and in a sample of the same materia…
Neutron scattering study of the effects of dopant disorder on the superconductivity and magnetic order in stage-4 La_2CuO_{4+y}
Y. S. Lee, F. C. Chou, A. Tewary +3
We report neutron scattering measurements of the structure and magnetism of stage-4 La_2CuO_{4+y} with T_c ~42 K. Our diffraction results on a single crystal sample demonstrate tha…
Effect of a magnetic field on long-range magnetic order in stage-4 and stage-6 superconducting La2CuO(4+y)
B. Khaykovich, R. J. Birgeneau, F. C. Chou +7
We have measured the enhancement of the static incommensurate spin-density wave (SDW) order by an applied magnetic field in stage-4 and stage-6 samples of superconducting La2CuO(4+…
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…
