Thermopower enhancement by encapsulating cerium in clathrate cages
A. Prokofiev, A. Sidorenko, K. Hradil +6
The increasing worldwide energy consumption calls for the design of more efficient energy systems. Thermoelectrics could be used to convert waste heat back to useful electric energ…
Field-induced charge-density-wave transitions in the organic metal -(BEDT-TTF)KHg(SCN) under hydrostatic pressure
D. Andres, M. V. Kartsovnik, W. Biberacher +3
Successive magnetic-field-induced charge-density-wave transitions in the molecular conductor -(BEDT-TTF)KHg(SCN) are studied in the hydrostatic pressure regime, in which…
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…
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…
Direct evidence for superconductivity in the organic charge density-wave compound alpha-(BEDT-TTF)_2KHg(SCN)_4 under hydrostatic pressure
D. Andres, M. V. Kartsovnik, W. Biberacher +2
We present direct evidence of a superconducting state existing in the title compound below 300 mK under quasi-hydrostatic pressure. The superconducing transition is observed in the…
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…
