Hall-effect evolution across a heavy-fermion quantum critical point
S. Paschen, T. Luhmann, S. Wirth +6
A quantum critical point (QCP) develops in a material at absolute zero when a new form of order smoothly emerges in its ground state. QCPs are of great current interest because of…
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…
Divergence of the Heavy Quasiparticle Mass at the Antiferromagnetic Quantum Critical Point in YbRh_2Si_2
P. Gegenwart, J. Custers, T. Tayama +4
We report low temperature specific heat, C, magnetization, M, susceptibility, chi, and electrical resistivity, rho, measurements on high-quality single crystals of the heavy-fermio…
Spin dynamics in a structurally ordered non-Fermi liquid compound: YbRh_2Si_2
K. Ishida, D. E. MacLaughlin, O. O. Bernal +5
Muon spin relaxation (muSR) experiments have been carried out at low temperatures in the non-Fermi-liquid heavy-fermion compound YbRh_2Si_2. The longitudinal-field muSR relaxation…
Magnetic-Field Induced Quantum Critical Point in YbRhSi
P. Gegenwart, J. Custers, C. Geibel +5
We report low-temperature calorimetric, magnetic and resistivity measurements on the antiferromagnetic (AF) heavy-fermion metal YbRhSi ( 70 mK) as a function of ma…
Study of the Ce(RhPd)Si alloy: evidence for itinerant character of the magnetic order in CeRhSi
M. Gomez Berisso, P. Pedrazzini, J. G. Sereni +3
We present electrical resistivity and specific heat measurements of alloys on the Rh rich side of the phase diagram of the Ce(RhPd)Si system and compare the res…
