Isotropic Quantum Scattering and Unconventional Superconductivity
Tuson Park, V. A. Sidorov, F. Ronning +7
Superconductivity without phonons has been proposed for strongly correlated electron materials that are tuned close to a zero-temperature magnetic instability of itinerant charge c…
Divergence of the Magnetic Grüneisen Ratio at the Field-Induced Quantum Critical Point in YbRhSi
Y. Tokiwa, T. Radu, P. Gegenwart +2
The heavy fermion compound YbRhSi is studied by low-temperature magnetization and specific-heat measurements at magnetic fields close to the quantum critical…
Multiple energy scales at a quantum critical point
P. Gegenwart, T. Westerkamp, C. Krellner +6
We report thermodynamic measurements in a magnetic-field-driven quantum critical point of a heavy fermion metal, YbRhSi. The data provide evidence for an energy scale in th…
Low Temperature Thermodynamic Properties of the Heavy Fermion Compound YbAgGe Close to the Field-Induced Quantum Critical Point
Y. Tokiwa, A. Pikul, P. Gegenwart +3
We present temperature and field dependent heat capacity and magnetization data taken at temperatures down to 50 mK and in an applied magnetic field up to 11.5 Tesla for YbAgGe, a…
Ferromagnetic quantum critical fluctuations in YbRh_2(Si_{0.95}Ge_{0.05})_2
P. Gegenwart, J. Custers, Y. Tokiwa +2
The bulk magnetic susceptibility of YbRh(SiGe) has been investigated %by ac-and dc-magnetometry at low temperatures and close to the field-induce…
Scaling of the magnetic entropy and magnetization in YbRh_2(Si_{0.95}Ge_{0.05})_2
P. Gegenwart, Y. Tokiwa, K. Neumaier +2
The magnetic entropy of YbRh_2(Si_{0.95}Ge_{0.05})_2 is derived from low-temperature ( mK) specific heat measurements. Upon field-tuning the system to its antiferromagnet…
