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…
Magnetic phase transitions in the two-dimensional frustrated quantum antiferromagnet Cs2CuCl4
Y. Tokiwa, T. Radu, R. Coldea +3
We report magnetization and specific heat measurements in the 2D frustrated spin-1/2 Heisenberg antiferromagnet Cs2CuCl4 at temperatures down to 0.05 K and high magnetic fields up…
Bose-Einstein Condensation of Magnons in Cs2CuCl4
T. Radu, H. Wilhelm, V. Yushankhai +5
We report on results of specific heat measurements on single crystals of the frustrated quasi-2D spin-1/2 antiferromagnet Cs_2CuCl_4 (T_N=0.595 K) in external magnetic fields B<12…
Field-induced suppression of the heavy-fermion state in YbRh_2Si_2
Y. Tokiwa, P. Gegenwart, T. Radu +4
We report DC magnetization measurements on YbRh_2Si_2 at temperatures down to 0.04K, magnetic fields B<11.5T and under hydrostatic pressure P<1.3GPa. At ambient pressure a kink at…
