We report high magnetic field measurements of magnetic torque, thermoelectric power, magnetization, and the de Haas-van Alphen effect in CeIrIn_{5} across 28 T, where a metamagnetic transition was suggested in previous studies. The thermoelectric power displays two maxima at 28 and 32 T. Above 28 T, a new, low de Haas-van Alphen frequency with a strongly enhanced effective mass emerges, while t...

We describe experiments in steady magnetic fields up to 33 T at low-temperatures on low-dimensional organic metals where the Landau level separation becomes greater than either the thermal or the impurity broadening. High precision, simultaneous Shubnikov—de Haas and de Haas—van Alphen measurements allow direct correlation of the oscillations of the magnetization with the dissipation as the Lan...

We predict the existence of Einstein-de Haas effect in topological magnon insulators. Temperature variation angular momentum state shows a sign change behavior, akin to low temperature thermal Hall conductance response. This manifests itself as macroscopic mechanical rotation material hosting magnons. show that an experimentally observable can be measured square-octagon, kagome, and honeycomb l...

This contribution addresses the remote sensing chapter of the USE HAAS Study, a Specific Support Action of the European Union Sixth Framework Program, aiming at producing a Strategic Research Agenda for High Altitude Aircraft and Airships. After a brief presentation of the objectives and methodology of the USE HAAS Study, the Strategic Research Agenda for remote sensing shall be addressed by co...

The quantum de Haas-van Alphen (dHvA) and Shubnikov-de Haas oscillations measured in graphite were decomposed by pass-band filtering onto contributions from three different groups of carriers. Generalizing the theory of dHvA oscillations for 2D carriers with an arbitrary spectrum and by detecting the oscillation frequencies using a method of two-dimensional phase-frequency analysis which we dev...

The de Haas-van Alphen effect in the vortex state of the type-II superconductors 2H-NbSe2 and V3Si is studied. We discuss the experimental and theoretical considerations pertaining to the observation of such oscillations. Macroscopic pinning of the flux lattice cannot explain the observed attenuation of quantum oscillations in the mixed state. A critical comparison of our measurements with the ...
