75. Exploring the third dimension in Magnonic Crystals

Gianluca Gubbiotti (Istituto Officina dei Materiali - CNR)

09/09/2019, 08:30

Keynote

Magnonic crystals (MCs) are materials with periodically modulated magnetic properties where the spin waves (SWs) band structure consists of intervals of allowed SW frequencies and forbidden gaps in which there are no allowed magnonic states.
In the recent past, most of the studies have been focused on planar nanostructures where the magnetic constituents have the same thickness, while, to the...

14. The short-range order in Zr-Ti melts

Sandro Szabó (Heinz Maier-Leibnitz Center (MLZ) and Physics Department, Technical University of Munich)

10/09/2019, 08:30

Keynote

The early transition metals Zirconium and Titanium show very similar chemical and structural properties. Alloyed they compose a completely miscible system, which is the boundary binary system for many bulk metallic glasses (BMGs) and stable quasi-crystals. However, the detailed formation mechanisms of these special structures remain largely unknown and are often speculative. Here, accurate...

26. Near-field THz nanoscopy with novel accelerator-based photon sources

Lukas M. Eng (Institute of Applied Physics, School of Science, TU Dresden, 01062 Dresden, Germany)

10/09/2019, 11:10

Keynote

This talk advertises scattering-type scanning near-field infrared nanospectroscopy (s-SNIM) in the spectral range of 75 to 1.2 THz [1,2], as provided by the free-electron laser FELBE at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Germany. By combining s-SNIM with FELBE, we demonstrate a -independent optical resolution of ~10 nm only, by exploring structured Au samples,...

72. Structural phase transitions from first-principles calculations

Ion Errea (University of the Basque Country)

11/09/2019, 08:30

Keynote

Describing atomic vibrations from first-principles accurately is of paramount importance to
understand the thermodynamic and transport properties of solids, especially to understand
structural phase transitions. Phonon dispersions are routinely calculated within the harmonic
approximation, and transport properties can be studied by estimating the electron-phonon
and phonon-phonon interactions...

55. Metal oxide heterostructures and hybrid nano composite for chemical sensors

Elisabetta Comini

12/09/2019, 08:30

Keynote

In the field of advanced sensor technology, metal oxide nanostructures are promising materials due to their high charge carrier mobility, easy fabrication and excellent stability. In particular, most of them exhibit a reversible interaction between their surfaces with the surrounding atmosphere. This interaction may lead to a change of some different properties of the material, such as...
