Structural, transport, magnetic, and thermal properties of Eu8Ga16Ge30
- S. Paschen, W. Carrillo‐Cabrera, +4 authors F. Steglich
- Materials Science
- 1 November 2001
${\mathrm{Eu}}_{8}{\mathrm{Ga}}_{16}{\mathrm{Ge}}_{30}$ is the only clathrate known so far where the guest positions are fully occupied by a rare-earth element. Our investigations show that, in… Expand
Low-temperature transport, thermodynamic, and optical properties of FeSi
- S. Paschen, E. Felder, +6 authors Z. Fisk
- Materials Science
- 15 November 1997
We present a comprehensive series of electrical transport ~conductivity, magnetoresistance, and Hall effect!, thermodynamic ~specific heat, magnetic susceptibility, and magnetization!, and optical… Expand
Hall-effect evolution across a heavy-fermion quantum critical point
- S. Paschen, T. Lühmann, +6 authors Q. Si
- Chemistry, Medicine
- Nature
- 3 November 2004
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 their singular… Expand
Thermal conductivity of thermoelectric clathrates
- A. Bentien, M. Christensen, +5 authors B. Iversen
- Physics
- 16 January 2004
Transport properties of ${\mathrm{Ba}}_{8}{\mathrm{Ga}}_{16}{\mathrm{Ge}}_{30}$ single-crystalline samples prepared with an excess of Ga are presented. The excess Ga does not only produces p-type… Expand
Are type-I clathrates Zintl phases and 'phonon glasses and electron single crystals'?
- S. Paschen, V. Pacheco, +6 authors F. Steglich
- Materials Science
- 1 April 2003
Abstract We discuss to which extent the concepts of Zintl phases and of ‘phonon glasses and electron single crystals’ apply to type-I clathrates. In (β-) Eu 8 Ga 16 Ge 30 the presence of residual… Expand
New type-I clathrates with ordered Eu distribution
- S. Paschen, S. Budnyk, +4 authors Y. Grin
- Materials Science
- 15 August 2006
Abstract In our search for clathrates containing rare-earth elements we have discovered the three new clathrate-I phases K 6 Eu 2 Ga 10 Ge 36 , K 6 Eu 2 Zn 5 Ge 41 , and K 6 Eu 2 Cd 5 Ge 41 . The Eu… Expand
Multiple Energy Scales at a Quantum Critical Point
- P. Gegenwart, T. Westerkamp, +6 authors Q. Si
- Chemistry, Medicine
- Science
- 25 April 2006
We report thermodynamic measurements in a magnetic-field-driven quantum critical point of a heavy fermion metal, YbRh2Si2. The data provide evidence for an energy scale in the equilibrium excitation… Expand
Atomic ordering and thermoelectric properties of the n-type clathrate Ba8Ni3.5Ge42.1square0.4.
- L. T. Nguyen, U. Aydemir, +11 authors S. Paschen

- Dalton transactions
- 11 January 2010
Single crystals of the type-I clathrate Ba(8)Ni(3.5)Ge(42.1)square(0.4) (space group Pm3n, no. 223, a = 10.798(2) A, l = 30 mm, slashed circle = 8 mm) were grown from the melt using the Bridgman… Expand
Destruction of the Kondo effect in the cubic heavy-fermion compound Ce3Pd20Si6.
- J. Custers, K. Lorenzer, +9 authors S. Paschen
- Physics, Medicine
- Nature materials
- 1 March 2012
How ground states of quantum matter transform between one another reveals deep insights into the mechanisms stabilizing them. Correspondingly, quantum phase transitions are explored in numerous… Expand
