Complex Magnetic Behavior of the Ce sawtooth chains in CeRhSn
P. Opletal, J. Fikáček, E. Duverger-Nédellec +8
Conflicting reports exist on the ground state of the intermetallic compound CeRhSn. This can be rooted in the sawtooth-like arrangement of two inequivalent Ce sites in the unit…
Dramatic elastic response at the critical end point in UTe
Michal Vališka, Tetiana Haidamak, Andrej Cabala +10
The first-order transition line in the \textit{H-T} phase diagram of itinerant electron metamagnets terminates at the critical end point-analogous to the critical point on the gas-…
Anomalous vortex dynamics in spin-triplet superconductor UTe
Y. Tokiwa, H. Sakai. S. Kambe, P. Opletal +7
The vortex dynamics in the spin-triplet superconductor, UTe, are studied by measuring the DC electrical resistivity with currents along the -axis under magnetic fields along…
Ferromagnetic Crossover within the Ferromagnetic Order of UTe
Petr Opletal, Hironori Sakai, Yoshinori Haga +4
We investigate the physical properties of a single crystal of uranium telluride UTe. We have confirmed that UTe crystallizes in the hexagonal structure wi…
First Observation of de Haas-van Alphen Effect and Fermi Surfaces in Unconventional Superconductor UTe2
Dai Aoki, Hironori Sakai, Petr Opletal +11
We report the first observation of the de Haas-van Alphen (dHvA) effect in the novel spin-triplet superconductor UTe2 using high quality single crystals with the high residual resi…
Slow Electronic Dynamics in the Paramagnetic State of UTe
Yo Tokunaga, Hironori Sakai, Shinsaku Kambe +13
Te NMR experiments in field () applied along the easy magnetization axis (the -axis) revealed slow electronic dynamics developing in the paramagnetic state of UTe…
Different universality classes of isostructural U compounds ( = Rh, Co, CoRu; = Ga, Al)
Petr Opletal, Vladimír Sechovský, Jan Prokleška
Magnetization isotherms of the 5f-electron ferromagnets URhGa, UCoGa and UCo0.98Ru0.02Al were measured at temperatures in the vicinity of their Curie temperature in order to invest…
Localization of 5f-electrons and pressure effects on magnetism in U intermetallics in the light of spin-fluctuation theory
Petr Opletal, Jaroslav Valenta, Petr Proschek +2
UCoGa and URhGa, two isostructural compounds show opposite signs of the initial response of Curie temperature to applied hydrostatic premenssure. To determine the physical origin o…
Antiferromagnetism and phase transitions in non-centrosymmetric UIrSi
Jaroslav Valenta, Fuminori Honda, Michal Vališka +7
Magnetization and specific heat measurements on a UIrSi3 single crystal reveal Ising-like antiferromagnetism below T = 41.7 K with easy magnetization direction along the c-axis…
Properties and Collapse of the Ferromagnetism in UCo1-xRuxAl Studied in Single Crystals
Jiri Pospisil, Petr Opletal, Michal Valiska +10
We have investigated the ferromagnetic (FM) phase which suddenly develops in UCo1-xRuxAl and is isolated by paramagnetic regions on both sides from the parent UCoAl and URuAl. For…
