Neutron Depolarization due to Ferromagnetism and Spin Freezing in CePdRh
M. Seifert, P. Schmakat, M. Schulz +5
We report neutron depolarization measurements of the suppression of long-range ferromagnetism and the emergence of magnetic irreversibilities and spin freezing in CePdRh$_x…
Femtosecond pump-probe absorption edge spectroscopy of cubic GaN
Elias Baron, Rüdiger Goldhahn, Shirly Espinoza +6
Time-dependent femtosecond pump-probe spectroscopic ellipsometry studies on zincblende gallium-nitride (zb-GaN) are performed and analyzed between 2.9-3.7eV. An ultra-fast change o…
Extremely low energy ARPES of quantum well states in cubic-GaN/AlN and GaAs/GaAlAs heterostructures
Mahdi Hajlaoui, Stefano Ponzoni, Michael Deppe +6
Quantum well (QW) heterostructures have been extensively used for the realization of a wide range of optical and electronic devices. Exploiting their potential for further improvem…

Kondo-Cluster-Glass State near a Ferromagnetic Quantum Phase Transition
T. Westerkamp, M. Deppe, R. Kuechler +5
We report on a comprehensive study of CePdRh poly- and single crystals close to the ferromagnetic instability by means of low-temperature ac su…
Non-Fermi liquid states in the pressurized system: two critical points
H. Q. Yuan, F. M. Grosche, M. Deppe +3
In the archetypal strongly correlated electron superconductor CeCuSi and its Ge-substituted alloys CeCu(SiGe) two quantum phase transitions -- one mag…
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…
