Structural Phase Transition in the 2D Spin Dimer Compound SrCu2(BO3)2
K. Sparta, G. J. Redhammer, P. Roussel +11
A displacive, 2nd order structural phase transition at Ts=395 K from space group I`4 2 m below Ts to I 4/m c m above Ts has been discovered in the two-dimensional spin dimer compou…
Asymmetric flux pinning in laterally nanostructured ferromagnetic / superconducting bilayers
M. Lange, M. J. Van Bael, L. Van Look +5
We investigated the pinning of flux lines in a superconducting film by a regular array of magnetic antidots. The sample consists of a Co/Pt multilayer with perpendicular magnetic a…
Collective Singlet Excitations and Evolution of Raman Spectral Weights in the 2D Spin Dimer Compound SrCu2(BO3)2
Peter Lemmens, M. Grove, M. Fischer +5
We present a Raman light scattering study of the two-dimensional quantum spin system SrCu2(BO3)2 and show that the magnetic excitation spectrum has a rich structure, including seve…
