Fast and ultrafast electron microscopies for skyrmions and plasmonics

In recent years, topology gained a central role in physics. We learnt that energetics could be often explained better by classes of objects defined by having qualitative differences. In today's jargon, we say they are topologically distinct. The process of ...

Soft-phonon driven hexagonal-orthorhombic phase transition in BaVS3

Helmuth Berger

The lattice dynamics of low-dimensional BaVS3 is reported across the hexagonal-orthorhombic phase transition occurring at T-S = 250 K using a combination of the thermal diffuse scattering of x rays, inelastic x-ray scattering, and density functional theory ...

Resonant inelastic X-ray scattering of magnetic excitations under pressure

Matteo Rossi

Resonant inelastic X-ray scattering (RIXS) is an extremely valuable tool for the study of elementary, including magnetic, excitations in matter. The latest developments of this technique have mostly been aimed at improving the energy resolution and perform ...

Reading and writing single-atom magnets

Donat Fabian Natterer

The single-atom bit represents the ultimate limit of the classical approach to high-density magnetic storage media. So far, the smallest individually addressable bistable magnetic bits have consisted of 3-12 atoms(1-3). Long magnetic relaxation times have ...

Nonequilibrium Dynamics of Collective Excitations in Strongly Interacting and Correlated Quantum Systems

Edoardo Baldini

Revealing the emergence and the dynamics of collective excitations in complex matter is a subject of pivotal importance, as it provides insight into the strength and spatial distribution of interactions and correlations. At the same time, collectivity lies ...

Simultaneous electronic and the magnetic excitation of a ferromagnet by intense THz pulses

Christoph Peter Hauri, Mostafa Shalaby

The speed of magnetization reversal is a key feature in magnetic data storage. Magnetic fields from intense THz pulses have been recently shown to induce small magnetization dynamics in a cobalt thin film on the sub-picosecond time scale. Here, we show tha ...

Optically switched magnetism in photovoltaic perovskite CH3NH3(Mn:Pb)I-3

László Forró, Oleg Yazyev, Endre Horvath, Alla Arakcheeva, Bálint Náfrádi, Massimo Spina, Péter Szirmai

The demand for ever-increasing density of information storage and speed of manipulation boosts an intense search for new magnetic materials and novel ways of controlling the magnetic bit. Here, we report the synthesis of a ferromagnetic photovoltaic CH3NH3 ...
