S. Rößler, S. Wirth, MPI CPfS Dresden and Y. Skourski, HLD Dresden In recent years, the iron chalcogenides received considerable attention in the condensed-matter physics community which was mainly sparked by the discovery of superconductivity below Tc ≈ 8.5 K in bulk FeSe. The binary sister compound Fe1+yTe is [...]
Michal Baranowski and Paulina Plochocka, LNCMI-Toulouse Organic-inorganic halide perovskites have become the “next big thing” in emerging semiconductor materials, with their unprecedented rapid development and successful application in high-performance photovoltaics. Yet, their inherent instabilities with respect to moisture remain a crucial challenge for these materials. This directed the interest [...]
LNCMI - Toulouse. Published on Feb 13, 2020. I joined the LNCMI Toulouse last September, but I am not completely new, as I made a short stay in this laboratory quite a long time ago now! At that time, together with Loic Drigo, we developed a contactless measurement method [...]
Lisa Rossi and Ben Bryant, HFML Nijmegen Frustrated magnets are materials with competing spin interactions, which cannot be simultaneously satisfied. While these materials have become most famous as a playground for novel phases, such as quantum spin liquids, they also exhibit technologically relevant properties, such as multiferroicity and an [...]
Toshihiro Nomura* and Sergei Zherlitsyn, HLD Dresden. A quartz-crystal microbalance (QCM) is an ultrasensitive device to detect changes of the mass. When an external mass is coupled to the surface of the quartz micromembrane, the resonance frequency f0 of the QCM decreases. Owing to the high quality factor, Q, [...]
Milan Orlita, LNCMI-Grenoble. When a magnetic field is applied to a solid, the continuous density of electronic states transforms into a set of discrete energy levels, known as Landau levels. Electrons excited in such a ladder may recombine, with emission of photons. This process can be viewed as the [...]
