Anisotropic Colossal Magnetoresistance Effects in Fe_{1-x}Cu_xCr_2S_4
V. Fritsch, J. Deisenhofer, R. Fichtl +9
A detailed study of the electronic transport and magnetic properties of FeCuCrS () on single crystals is presented. The resistivity is investigated…
Approaching quantum criticality in a partially geometrically frustrated heavy-fermion metal
V. Fritsch, N. Bagrets, G. Goll +5
Quantum phase transitions have captured the interest of a large community in condensed-matter and atom physics research. The common feature of these very different material classes…
Strongly Anisotropic Magnetic Phase Diagram of CeAu2Ge2
V. Fritsch, P. Pfundstein, P. Schweiss +3
CeAu2Ge2 single crystals (tetragonal ThCr2Si2 structure) have been grown in Au-Ge flux (AGF) as well as in Sn flux (SF). X-ray powder-diffraction and EDX measurements indicate that…
Spin-liquid signatures in the quantum critical regime of pressurized CePdAl
M. Majumder, R. Gupta, H. Luetkens +4
CePdAl is a prototypical frustrated Kondo lattice with partial long-range order (LRO) at K. Previous bulk experiments under hydrostatic pressure found signatures…
Photoemission study of polycrystalline Gd_{1-x}Sr_xTiO_{3+delta}: correlation and surface effects
M. Sing, M. Karlsson, D. Schrupp +6
We report photoemission studies of polycrystalline samples of Sr-doped GdTiO_{3+delta}, which undergoes a Mott-Hubbard-like metal-insulator transition at a Ti-concentration of abou…
Crystal-field effects in the mixed-valence compounds Yb2M3Ga9 (M= Rh, Ir)
N. O. Moreno, A. Lobos, A. A. Aligia +8
Magnetic susceptibility, heat capacity, and electrical resistivity measurements have been carried out on single crystals of the intermediate valence compounds Yb2Rh3Ga9 and Yb2Ir3G…
