Pressure-induced change of the pairing symmetry in superconducting CeCu2Si2

E. Lengyel, M. Nicklas, H. S. Jeevan +5

Low-temperature (T) heat-capacity measurements under hydrostatic pressure of up to p=2.1 GPa have been performed on single-crystalline CeCu2Si2. A broad superconducting (SC) region…

Rare earth magnetism in CeFeAsO: A single crystal study

A. Jesche, C. Krellner, M. de Souza +2

Single crystals of CeFeAsO, large enough to study the anisotropy of the magnetic properties, were grown by an optimized Sn-flux technique. The high quality of our single crystals i…

Development of the critical exponent at the antiferromagnetic phase transition of YbRh2Si2 under chemical pressure

C. Krellner, C. Klingner, C. Geibel +1

We present specific-heat measurements in the vicinity of the antiferromagnetic phase transition on single crystals of the alloy Yb(Rh_{1-x}Co_x)2Si2 for x<= 0.38. This study was mo…

Spin correlations and exchange in square lattice frustrated ferromagnets

M. Skoulatos, J. P. Goff, C. Geibel +8

The J1-J2 model on a square lattice exhibits a rich variety of different forms of magnetic order that depend sensitively on the ratio of exchange constants J2/J1. We use bulk magne…
