High- superconductor candidates proposed by machine learning

open access: yesMachine Learning: Science and Technology
We cast the relation between the chemical composition of a solid-state material and its superconducting critical temperature ( $T_\mathrm c$ ) as a statistical learning problem with reduced complexity.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Ferromagnetism of Molecular Beam Epitaxy‐grown Ultra‐thin Cr2Ge2Te6 Films Down to the Monolayer Limit on Si Substrates

open access: yesAdvanced Materials, EarlyView.
Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

Formation of (Tl1-x Crx)Sr2CaCu2O7-δ (Tl-1212) Superconducting Phase Using Cr2S3

open access: yesInternational Journal of Electrochemical Science, 2013
The use of Cr2S3 to prepare the (Tl1-x Crx)Sr2CaCu2O7-δ (Tl-1212) superconductor phase is discussed. Samples with nominal starting composition (Tl1-x Crx)Sr2CaCu2O7-δ (Tl-1212) for x = 0.05, 0.10, 0.15, 0.20, 0.25 and 0.30 were prepared by the solid ...

Vortices and chirality in multi-band superconductors

open access: yes, 2012
We investigate several important properties of multi-band superconductors. They are time-reversal symmetry breaking, chirality and fractional quantum flux vortices in three-band superconductors.

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry

open access: yesAdvanced Materials Interfaces, EarlyView.
We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Properties Of MgB2/Ga Composites Prepared By Mechanical Alloying

open access: yesArchives of Metallurgy and Materials, 2015
In this study, we examined the effect of Ga-doping and mechanical alloying in MgB2 on microstructural and phase evolution. A comparison was made between in-situ and ex-situ processed Mg-B-Ga samples.

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...
