Experimental observation of repulsively bound magnons
Zhe Wang, Catalin-Mihai Halati, Jean-Sébastien Bernier +9
Stable composite objects, such as hadrons, nuclei, atoms, molecules and superconducting pairs, formed by attractive forces are ubiquitous in nature. By contrast, composite objects…
Crystal melting influenced by particle cooperativity of the liquid
P. Lunkenheimer, K. Samwer, A. Loidl
Recently, a universal relation between the thermal expansion coefficient of glasses , their glass-transition temperature Tg, and the so-called fragility index m of the corresp…
Manipulating surface magnetic order in iron telluride
Christopher Trainer, Chi Ming Yim, Christoph Heil +7
Control of emergent magnetic orders in correlated electron materials promises new opportunities for applications in spintronics. For their technological exploitation, it is importa…
Magnetism of PdNi alloys near the critical concentration for ferromagnetism
G. M. Kalvius, O. Hartmann, R. Wäppling +11
We report results of a muon spin rotation and relaxation (SR) study of dilute PdNi alloys, with emphasis on Ni concentrations 0.0243 and 0.025. These are close…
Absence of polar order in LuFe2O4
A. Ruff, S. Krohns, F. Schrettle +3
LuFe2O4 often is considered as a prototypical multiferroic with polar order arising from the electronic degrees of freedom only ("electronic ferroelectricity"). In the present work…
Optical conductivity of superconducting Rb2Fe4Se5
A. Charnukha, J. Deisenhofer, D. Pröpper +8
We report the complex dielectric function of high-quality nearly-stoichiometric Rb2Fe4Se5 (RFS) single crystals with Tc=32 K determined by wide-band spectroscopic ellipsometry and…
Spin liquid in a single crystal of the frustrated diamond lattice antiferromagnet CoAl2O4
O. Zaharko. N. B. Christensen, A. Cervellino, V. Tsurkan +7
We study spin liquid in the frustrated diamond lattice antiferromagnet CoAl2O4 by means of single crystal neutron scattering in zero and applied magnetic field. The magnetically or…
Evolution of magnetic states in frustrated diamond lattice antiferromagnetic Co(Al1-xCox)2O4 spinels
O. Zaharko, A. Cervellino, V. Tsurkan +2
Using neutron powder diffraction and Monte-Carlo simulations we show that a spin-liquid regime emerges at $all compositions in the diamond-lattice antiferromagnets Co(Al1-xCox)2O4.…
