An excellent soft magnetic Fe/Fe3O4-FeSiAl composite with high permeability and low core loss

Results in Physics, 2019
It is well know that the high temperature annealing can improve the permeability and reduce the hysteresis loss of soft magnetic composites (SMCs), but the eddy current loss would be accordingly increased. Thus, developing SMCs with high permeability and

In-wheel axial-flux SRM drive for light electric vehicles [PDF]

, 2018
Revenues from global sales of light electric vehicles are expected to grow from $ 9.3 billion in 2017 to $ 23.9 billion in 2025. In order to boost this growth electric drives with better features and lower costs have to be developed.

Effect of "dipolar-biasing" on the tunability of tunneling magnetoresistance in transition metal oxide systems

, 2012
We observe an unusual tunneling magnetoresistance (TMR) phenomenon in a composite of La$_{2/3}$Sr$_{1/3}$MnO$_{3}$ with CoFe$_{2}$O$_{4}$ where the TMR versus applied magnetic field loop suggests a "negative coercive field". Tracing its origin back to a "

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Stretchable Magneto-Mechanical Configurations with High Magnetic Sensitivity Based on “Gel-Type” Soft Rubber for Intelligent Applications

Gels
“Gel-type” soft and stretchable magneto-mechanical composites made of silicone rubber and iron particles are in focus because of their high magnetic sensitivity, and intelligence perspective. The “intelligence” mentioned here is related to the “smartness”

3D vector magnetic properties of soft magnetic composite material [PDF]

Journal of Magnetism and Magnetic Materials, 2006
Abstract Even under one-dimensional (1D) alternating or 2D rotating magnetic excitation, a magnetic material shows 3D magnetic property due to the rotation of magnetic domains. Only when the 3D properties are properly considered the understanding and modelling of the magnetisation process can be complete.

Advancing Electronic Application of Coordination Solids: Enhancing Electron Transport and Device Integration via Surface‐Mounted MOFs (SURMOFs)

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...
