Publikováno v: Physical Review Research, Vol 2, Iss 1, p 013183 (2020)

Magnetic frustration in metals is scarce and hard to pinpoint, but exciting due to the possibility of the emergence of fascinating novel phases. The cubic intermetallic compound HoInCu_{4} with all holmium atoms on an fcc lattice exhibits partial mag

Ternary Compounds in the Sn-Rich Section of the Ba–Ga–Sn System: Ba8Ga16–xSn30+x (1.1 ≤ x ≤ 2.8) Clathrates of Type-I and Type-VIII, and BaGa2–xSn4+x (x ≈ 0.2) with a Clathrate-like Structure

Publikováno v: Crystals, Vol 1, Iss 3, Pp 145-162 (2011)

Systematic syntheses in the Ba–Ga–Sn system confirmed the existence of a new ternary phase BaGa1.79Sn4.21(2) (EuGa2Ge4 structure type; orthorhombic space group Cmcm, Pearson symbol oS28) with lattice parameters a = 4.5383(6) Å, b = 12.2486(16) �

Indium Doping in BaSn3–x Inx (0 ≤ x ≤ 0.2) with Ni3Sn Structure

Autor: Marion C. Schäfer, Yuki Yamasaki, Veronika Fritsch, Svilen Bobev

Publikováno v: Crystals, Vol 1, Iss 3, Pp 104-111 (2011)

Investigations of the system Ba–In–Sn, with the objective to synthesize Ba8In16Sn30 clathrate using Sn and In flux reactions, yielded instead the known BaSn3 compound (P63/mmc; a = 7.228(2) Å, c = 5.469(3) Å) from Sn flux and its In-doped varia

Publikováno v: Physical Review B. 103

We study single crystals of the magnetic superconductor $\mathrm{Eu}\mathrm{Rb}{\mathrm{Fe}}_{4}{\mathrm{As}}_{4}$ by magnetization, electron spin resonance (ESR), angle-resolved photoemission spectroscopy, and electrical resistance in pulsed magneti

Publikováno v: Physical Review B. 100

$^{51}\mathrm{V}$ nuclear magnetic resonance (NMR) and magnetization studies on ${\mathrm{CeTi}}_{1\ensuremath{-}x}{\mathrm{V}}_{x}{\mathrm{Ge}}_{3}$ have been performed to explore the evolution from the ferromagnetic ($x=0.113$) to the antiferromagn

Publikováno v: Physical Review Letters. 121

The heavy-fermion compound ${\mathrm{CeCu}}_{6\ensuremath{-}x}{\mathrm{Au}}_{x}$ has become a model system for unconventional magnetic quantum criticality. For small Au concentrations $0\ensuremath{\le}xl0.16$, the compound undergoes a structural tra

Entropy Evolution in the Magnetic Phases of Partially Frustrated CePdAl

Autor: Akito Sakai, S. Wunderlich, Veronika Fritsch, Philipp Gegenwart, Hilbert von Löhneysen, Stefan Lucas, Chien-Lung Huang, E. L. Green, Kai Grube, Oliver Stockert, J. Wosnitza

Publikováno v: Physical Review Letters 118(2017), 107204

In the heavy-fermion metal CePdAl long-range antiferromagnetic order coexists with geometric frustration of one third of the Ce moments. At low temperatures the Kondo effect tends to screen the frustrated moments. We use magnetic fields $B$ to suppre

We report on a single-crystal neutron diffraction study of the evolution of the antiferromagnetic order in the heavy-fermion compound CePd$_{1-x}$Ni$_x$Al which exhibits partial geometric frustration due to its distorted Kagom\'e structure. The magne

CePdAl: a Kondo lattice with partial frustration

Autor: Stefan Lucas, Hilbert von Löhneysen, Philipp Gegenwart, Akito Sakai, Veronika Fritsch, Zita Huesges, W. Kittler, Christian Taubenheim, Björn Pedersen, Burkhard Schmidt, Oliver Stockert, Sarah Woitschach, Kai Grube

Publikováno v: Journal of physics / Conference Series, 807 (3), Art. Nr.: 032003

Magnetic frustration, which is well-defined in insulating systems with localized magnetic moments, yields exotic ground states like spin ices, spin glasses, or spin liquids. In metals magnetic frustration is less well defined because of the incipient
