U(1)-Symmetry breaking and violation of axial symmetry in TlCuCl3 and other insulating spin systems
Raffaele Dell'Amore, Andreas Schilling, Karl Kraemer
We describe the Bose-Einstein condensate of magnetic bosonic quasiparticles in insulating spin systems using a phenomenological standard functional method for T = 0. We show that r…
LaBaNiO4: A Fermi glass
A. Schilling, R. DellAmore, J. Karpinski +4
Polycrystalline samples of LaSr1-xBaxNiO4 show a crossover from a state with metallic transport properties for x = 0 to an insulating state as x -> 1. The end member LaBaNiO4 with…
The fraction of Bose-Einstein condensed triplons in TlCuCl3 from magnetization M(T,H)-data
R. Dell'Amore, K. Krämer, A. Schilling
In this study we calculate the fraction of condensed magnetic quasiparticles of TlCuCl3 from magnetization M(T,H)-data. It is independent of the direction of the magnetic field and…
Anisotropic field dependence of the magnetic transition in Cu2Te2O5Br2
A. V. Sologubenko, R. Dell'Amore, H. R. Ott +1
We present the results of measurements of the thermal conductivity of Cu2Te2O5Br2, a compound where tetrahedra of Cu^{2+} ions carrying S=1/2 spins form chains along the c-axis of…
