Structural variations and magnetic properties of the quantum antiferromagnets Cs2CuCl4-xBrx
Pham Thanh Cong, Bernd Wolf, Natalija van Well +4
Depending on the crystal growth conditions, an orthorhombic (O-type) or a tetragonal (T-type) structure can be found in the solid solution Cs2CuCl4-xBrx (0 < x < 4). Here we presen…
Evidence for a Kondo destroying quantum critical point in YbRh2Si2
Frank Steglich, Heike Pfau, Stefan Lausberg +10
The heavy-fermion metal YbRhSi is a weak antiferromagnet below K. Application of a low magnetic field T () is sufficient to conti…
Thermal and Electrical Transport across a Magnetic Quantum Critical Point
H. Pfau, S. Hartmann, U. Stockert +11
A quantum critical point (QCP) arises at a continuous transition between competing phases at zero temperature. Collective excitations at magnetic QCPs give rise to metallic propert…
Lifshitz transitions and quasiparticle de-renormalization in YbRhSi
H. R. Naren, S. Friedemann, G. Zwicknagl +4
We study the effect of magnetic fields up to 15 T on the heavy fermion state of YbRhSi via Hall effect and magnetoresistance measurements down to 50 mK. Our data show anoma…
Microwave spectroscopy on heavy-fermion systems: probing the dynamics of charges and magnetic moments
Marc Scheffler, Katrin Schlegel, Conrad Clauss +8
Investigating solids with light gives direct access to charge dynamics, electronic and magnetic excitations. For heavy fermions, one has to adjust the frequency of the probing ligh…
Magnetization study of the energy scales in YbRhSi under chemical pressure
Manuel Brando, Luis Pedrero, Tanja Westerkamp +4
We present a systematic study of the magnetization in YbRhSi under slightly negative (6?% Ir substitution) and positive (7% Co substitution) chemical pressure. We show…
