Formation of incommensurate long-range magnetic order in the Dzyaloshinskii-Moriya antiferromagnet BaCuGeO studied by neutron diffraction
S. Mühlbauer, G. Brandl, M. Månsson +1
Neutron diffraction on a triple-axis spectrometer and a small-angle neutron scattering instrument is used to study the magnetic phase transition in tetragonal BaCuGeO a…
Low-temperature ordered phases of the spin- XXZ chain system CsCoCl
O. Breunig, M. Garst, A. Rosch +6
In this study the magnetic order of the spin-1/2 XXZ chain system CsCoCl in a temperature range from 50 mK to 0.5 K and in applied magnetic fields up to 3.5 T is investigat…
The spin- XXZ chain system CsCoCl in a transverse magnetic field
O. Breunig, M. Garst, E. Sela +5
Comparing high-resolution specific heat and thermal expansion measurements to exact finite-size diagonalization, we demonstrate that CsCoCl for a magnetic field along the c…
Quantum bicriticality in the heavy-fermion metamagnet YbAgGe
Y. Tokiwa, M. Garst, P. Gegenwart +2
Bicritical points, at which two distinct symmetry-broken phases become simultaneously unstable, are typical for spin-flop metamagnetism. Interestingly, the heavy-fermion compound Y…
Universal signatures of the metamagnetic quantum critical endpoint: Application to CeRu2Si2
F. Weickert, M. Brando, F. Steglich +2
A quantum critical endpoint related to a metamagnetic transition causes distinct signatures in the thermodynamic quantities of a compound. We argue that, irrespective of the micros…
