Magnetocaloric effect and magnetic cooling near a field-induced quantum-critical point
B. Wolf, Y. Tsui, D. Jaiswal-Nagar +8
The presence of a quantum critical point (QCP) can significantly affect the thermodynamic properties of a material at finite temperatures T. This is reflected, e.g., in the entropy…
Distinct magnetic regimes through site-selective atom substitution in the frustrated quantum antiferromagnet CsCuClBr
P. T. Cong, B. Wolf, M. de Souza +11
We report on a systematic study of the magnetic properties on single crystals of the solid solution CsCuClBr (0 x 4), which include the two known end-…
Multi-step approach to microscopic models for frustrated quantum magnets - the case of the natural mineral azurite
Harald Jeschke, Ingo Opahle, Hem Kandpal +14
The natural mineral azurite Cu(CO)(OH) is a frustrated magnet displaying unusual and controversially discussed magnetic behavior. Motivated by the lack of a unified…
Synthesis, structural and physical properties of -FeSe
Mariano de Souza, Amir-Abbas Haghighirad, Ulrich Tutsch +2
We report on synthesis, structural characterization, resistivity, magnetic and thermal expansion measurements on the as yet unexplored -phase of FeSe, here synthesized…
Scaling theory of the Mott transition and breakdown of the Grüneisen scaling near a finite-temperature critical end point
Lorenz Bartosch, Mariano de Souza, Michael Lang
We discuss a scaling theory of the lattice response in the vicinity of a finite-temperature critical end point. The thermal expansivity is shown to be more singular than the specif…
Structural and magnetic transition in CeFeAsO: separated or connected?
A. Jesche, C. Krellner, M. de Souza +2
Using an adapted Sn-flux growth technique we obtained comparatively large CeFeAsO single crystals of better quality than previously reported polycrystals or single crystals, as evi…
