Invited Speaker / Conférencier invité

The generation and the detection of pure spin currents are fascinating challenges in modern solid state physics. In ferromagnet/normal metal thin film heterostructures, pure spin currents can be generated, e.g., by means of spin pumping [1], or via the application of thermal gradients in the so-called spin Seebeck effect [2]. An elegant scheme for detecting spin currents relies on the inverse...

Spatial inhomogeneity on the nanoscale is intrinsic to most thin film materials used in nanomagnetic technology, and can affect both static and dynamic magnetic responses [1]. Understanding the detailed effects of local inhomogeneity becomes increasingly important as device dimensions shrink. Focused ion beam irradiation is an elegant way to carry out local magnetic patterning to create highly...

Torque magnetometry using torsional resonators provides a highly sensitive platform for resolving magnetic signatures in single meso-scale elements. In the static case, sample magnetizations are biased using a DC field while an AC excitation is applied at a frequency equal to the mechanical resonance of the torsional device. The resulting torque is then measured using an interferometric...

Nanomechanical resonators are good sensors because of their small mass, high frequency and high quality factor. In particular for mass sensing, the adsorbent mass is estimated from the shift in mechanical resonance frequency. Fantastic progress has been made in mass sensitivity, reaching the single protein and even yoctogram mass level. Yet this technique alone is not sufficient to identify...
