Local moment magnon spectrum in conduction electron tunnelling
Peter Thalmeier, Alireza Akbari
The surface tunnelling spectrum of a dual system consisting of localised moments with antiferromagnetic order coupled to conduction electrons by on-site exchange interaction is inv…
Investigation of CeRhAs order parameters via ultrasound propagation anomalies
S. Galeski, C. Lee, F. Bartl +11
Unconventional superconductors with nearly degenerate pairing states are rare. CeRhAs has recently emerged as one of the few existing multi-phase superconductors. It exhibi…
Hyperfine coupling in singlet ground state magnets
Peter Thalmeier
The influence of hyperfine coupling to nuclear spins and of their quadrupolar splitting on the induced moment order in singlet ground state magnets is investigated. The latter are…
Magnetocalorics of singlet ground state induced moment magnets
Peter Thalmeier
In f-electron materials like Pr or U compounds with non-Kramers states of the f-shell the ground state may be a nonmagnetic singlet due to the action of the crystalline electric fi…
Image of helical local moment magnetic order in the STM spectrum
Alireza Akbari, Peter Thalmeier
The surface tunneling microscope (STM) method probes the itinerant conduction electron spectrum which is influenced by the presence of collective order parameters. It may in fact b…
Thermodynamics, elastic anomalies and excitations in the field induced phases of CeRh2As2
Peter Thalmeier, Alireza Akbari, Burkhard Schmidt
The tetragonal heavy fermion compound CeRh2As2 exhibits unconventional superconductivity accompanied by other broken symmetry phases that have been identified as presumably small m…
