Effect of Hydrostatic Pressure on the Kondo Effect in the Heavy Fermion System YbFeSi
Yogesh Singh, S. Ramakrishnan, C. Geibel
We report the effect of hydrostatic pressure on the resistivity of the heavy fermion Kondo lattice compound YbFeSi in the temperature range 2-300 K and in pressures upt…
Exotic superconductivity in the coexistent phase of antiferromagnetism and superconductivity in CeCu2(Si0.98Ge0.02)2: A Cu-NQR study under hydrostatic pressure
Y. Kawasaki, K. Ishida, S. Kawasaki +5
We report a pressure () effect on CeCu(SiGe) where an antiferromagnetic (AFM) order at 0.75 K coexists with superconductivity below $T_c \si…
Divergence of the Grueneisen Ratio at Quantum Critical Points in Heavy Fermion Metals
R. Kuechler, N. Oeschler, P. Gegenwart +8
We present low-temperature volume thermal expansion, , and specific heat, , measurements on high-quality single crystals of CeNi2Ge2 and YbRh2(SiGe) whi…
The break up of heavy electrons at a quantum critical point
J. Custers, P. Gegenwart, H. Wilhelm +7
The point at absolute zero where matter becomes unstable to new forms of order is called a quantum critical point (QCP). The quantum fluctuations between order and disorder that de…
Low temperature magnetic phase diagram of the cubic non-Fermi liquid system CeIn_(3-x)Sn_x
P. Pedrazzini, M. Gomez Berisso, J. G. Sereni +3
In this paper we report a comprehensive study of the magnetic susceptibility (χ), resistivity (ρ), and specific heat (C_P), down to 0.5 K of the cubic CeIn_(3-x)Sn_x alloy. The gro…
Tuning Heavy Fermion Systems into Quantum Criticality by Magnetic Field
P. Gegenwart, J. Custers, T. Tayama +8
We discuss a series of thermodynamic, magnetic and electrical transport experiments on the two heavy fermion compounds CeNi2Ge2 and YbRh2Si2 in which magnetic fields, B, are used t…
