Development of commercial soft and hard magnetic materials has been a history of unrelenting progress in alloy development and processing treatments. Starting from essentially zero a century ago, the economic impact due to all magnetic materials is now estimated to be 1.5% of the U.S. gross ...
MCE is an interesting effect and it is defined as the intrinsic property of magnetic materials which is expressed by temperature change (ΔT) of a magnetic material due to the application of a magnetic field54,55. Some authors have studied this concept as applied to several scenarios. Rastegar...

Micron-sized WC-metal (WC-0.6%C-21%Cr-6%Ni) powder was coated onto the substrate of magnetic bearing shaft material Inconel718 (substrate or In718) using JK3500 HVOF thermal sprayer for the improvement of the surface properties of the substrate. The optimal coating process for the highest sur...
Flexible materials have brought up a new era of application-based research in stretchable electronics and wearable devices in the last decade. Tuning of magnetic properties by changing the curvature of devices has significant impact in the new generation of sensor-based technologies. In this work, ...

The coercive force is the value of the magnetic field amplitude when the net magnetization in the direction of the field is zero and has a zero time rate of change. An equivalent definition of the coercive force is contained in the expression for the average instantaneous domain wall velocity;...
Nanocrystalline(FeCo/CoNbZr)n uniaxial-anisotropy soft magnetic multilayers were prepared by magnetron sputtering.CoNbZr amorphous layers act as grain refiners as well as soft magnetic grain-boundary materials for the FeCo layers.The resultant multilayer films exhibit excellent uniaxial-anisotropy soft magne...
