Photoemission Spectroscopy of Magnetic and Non-magnetic Impurities on the Surface of the BiSe Topological Insulator
T. Valla, Z. -H. Pan, D. R. Gardner +2
Dirac-like surface states on surfaces of topological insulators have a chiral spin structure that suppresses back-scattering and protects the coherence of these states in the prese…
Electronic Structure of the Topological Insulator Bi2Se3 Using Angle-Resolved Photoemission Spectroscopy: Evidence for a Nearly Full Surface Spin Polarization
Z. -H. Pan, E. Vescovo, A. V. Fedorov +5
We performed high-resolution spin- and angle-resolved photoemission spectroscopy studies of the electronic structure and the spin texture on the surface of BiSe, a model to…
Spin Dynamics of the Spin-1/2 Kagome Lattice Antiferromagnet ZnCu_3(OH)_6Cl_2
J. S. Helton, K. Matan, M. P. Shores +9
We have performed thermodynamic and neutron scattering measurements on the S=1/2 kagome lattice antiferromagnet Zn Cu_3 (OH)_6 Cl_2. The susceptibility indicates a Curie-Weiss temp…
Spin waves in the Frustrated Kagome Lattice Antiferromagnet KFe3(OH)6(SO4)2
K. Matan, D. Grohol, D. G. Nocera +5
The spin wave excitations of the ideal S=5/2 Kagome lattice antiferromagnet KFe3(OH)6(SO4)2 have been measured using high-resolution inelastic neutron scattering. We directly obser…
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…
