Magnetic Bound States in Dimerized Quantum Spin Systems
P. Lemmens, M. Fischer, M. Grove +5
Magnetic bound states are a general phenomenon in low dimensional antiferromagnets with gapped singlet states. Using Raman scattering on three compounds as dedicated examples we sh…

Electronic Raman scattering in Tl2Ba2CuO6+x: symmetry of the order parameter, oxygen doping effects, and normal state scattering
L. V. Gasparov, P. Lemmens, N. N. Kolesnikov +1
Single crystals of the optimally doped, moderately and strongly overdoped high temperature superconductor Tl2Ba2CuO6+x (Tl-2201) with Tc=80, 56 and 30K, respectively, have been inv…
