Magnetic Excitations in the Multiferroic Néel-type Skyrmion Host GaVS

Dieter Ehlers, Ioannis Stasinopoulos, Vladimir Tsurkan +6

Broadband microwave spectroscopy has been performed on single-crystalline GaVS, which exhibits a complex magnetic phase diagram including cycloidal, Néel-type skyrmion latt…

On the possibility of excitonic magnetism in Ir double perovskites

K. Pajskr, P. Novak, V. Pokorny +3

We combine several numerical and semi-analytical methods to study the double perovskites Sr2YIRO6 and Ba2YIRO6 which were recently proposed to exhibit excitonic magnetism. Sta…

Local Magnetism and Spin Dynamics of the Frustrated Honeycomb Rhodate Li2RhO3

P. Khuntia, S. Manni, F. R. Foronda +4

We report magnetization, heat capacity, 7Li - nuclear magnetic resonance (NMR), and muSR (muon spin roration) measurements on the honeycomb 4d5 spin liquid candidate Li2RhO3. The m…

Reversible Tuning of the Collapsed Tetragonal Phase Transition in CaFe2As2 by Separate Control of Chemical Pressure and Electron Doping

K. Zhao, C. Stingl, R. S. Manna +2

Single crystals of Ca(Fe1-xRux)2As2 (0<x<0.065) and Ca1-yLay(Fe0.973Ru0.027)2As2 (0<y<0.2) have been synthesized and studied with respect to their structural, electronic and magnet…

Charge instabilities of the two-dimensional Hubbard model with attractive nearest neighbour interaction

Raymond Fresard, Kevin Steffen, Thilo Kopp

Attractive non-local interactions jointly with repulsive local interaction in a microscopic modelling of electronic Fermi liquids generate a competition between an enhancement of t…
