Magnetic Materials: Chiral Spin Textures in Amorphous Iron–Germanium Thick Films (Adv. Mater. 8/2021)

Chiral Smectic C Liquid Crystal, Thick Sample Textures

The texture of ferroelectric chiral smectic liquid crystal confined between two aligning plates is studied in the case of thick samples i-esamples whose thickness is higher than the helical pitch. The helical texture with periodic unwinding discfination lines

Preliminary radiation tests of 32mm thick hydrogenated amorphous silicon films

Preliminary radiation tests of hydrogenated amorphous silicon n–i–p photodiodes deposited on a coated glass substrate are presented in this paper. These tests have been performed using a 24GeV proton beam. We report results on the fluence dependence of the diode dark current and of the signal induced by a proton spill.

Anomalous magnetic viscosity in bulk-amorphous materials

The demagnetization processes and the magnetic viscosity have been studied on a bulk-amorphous Nd 60 Fe 30 Al 10 rod at room temperature. Many unique magnetic properties have been found in this novel hard magnetic material. A clear hysteresis was present on the minor loops, though the total and irreversible susceptibilities exhibited single-phase magnet behavior. A signi"cant magnetic viscosity...

Observation of Unconventional Quantum Spin Textures in Topologically Ordered Materials

Retrieving spin textures on curved magnetic thin films with full-field soft X-ray microscopies

X-ray tomography is a well-established technique to characterize 3D structures in material sciences and biology; its magnetic analogue--magnetic X-ray tomography--is yet to be developed. Here we demonstrate the visualization and reconstruction of magnetic domain structures in a 3D curved magnetic thin films with tubular shape by means of full-field soft X-ray microscopies. The 3D arrangement of...
