Stress-Induced Grain Refinement in Hard Magnetic MnAl.C. Fabricated Using the Ball-Milling Method.

MnAl.C. flakes with different sizes were prepared with two distinct surfactant-assisted ball-milling methods using cylindrical and barrel containers.

Blockchain-based cloud manufacturing platforms: A novel idea for service composition in XaaS paradigm.

Cloud manufacturing is a new globalized manufacturing framework which has improved the performance of manufacturing systems. The service-oriented architecture as the main idea behind this framework means that all resources and capabilities are considered as services. The agents interact by way of service exchanging, which has been a part of service composition research topics.

Unusual interlayer quantum transport behavior caused by the zeroth Landau level in YbMnBi.

Relativistic fermions in topological quantum materials are characterized by linear energy-momentum dispersion near band crossing points. Under magnetic fields, relativistic fermions acquire Berry phase of π in cyclotron motion, leading to a zeroth Landau level (LL) at the crossing point, a signature unique to relativistic fermions. Here we report the unusual interlayer quantum transport behavior resulting from the zeroth LL mode observed in the time reversal symmetry breaking type II Weyl semimetal YbMnBi.

A magnetic topological semimetal SrMnSb (y, z < 0.1).

Weyl (WSMs) evolve from Dirac semimetals in the presence of broken time-reversal symmetry (TRS) or space-inversion symmetry. The WSM phases in TaAs-class materials and photonic crystals are due to the loss of space-inversion symmetry. For TRS-breaking WSMs, despite numerous theoretical and experimental efforts, few examples have been reported.
