Magnetic nanostructures have attracted a great deal of attention during the last decade because of their prospective applications not only in microwave absorption, high density recording media, and biosensor applications but also in functional micro and nanodevices [1-4]. Recently, significant investigations have been motivated to get excess of 1Tbit/in2 in magnetic storage devices but at smaller...
For the complex structure of the large capacity turbo-generator in end region, the accurate calculation of the leakage magnetic field became key factor in large generator design. Affected by the leakage magnetic field, there is a problem that the end stator ladder packets, copper screen, press plate has a local high temperature. The three-dimensional electromagnetic field of a 330 MW water-hydrogen-hydrogen...
Wireless Sensors Networks (WSNs) is the critical part of the Internet of Things (IOTs). However, most of the wireless sensors in WSNs also use batteries as their power supply. The finite battery life has limited the development and application of WSNs. The self-powering device could be a good solution, which performs both an energy harvester and wireless sense function. Vibrations with frequencies...
Diluted magnetic semiconductors (DMSs), which refer to transition-metal (TM) ions partially substitute cations of the host semiconductor materials, have attracted considerable attention for potential applications in spin electronics and magnetic devices. Aiming in realizing practical spintronic devices, the most important is to develop DMSs with Curie temperature (TC) exceeding room temperature. And...
The NdFeB magnets with millimeter sizes, typically between 0.5 and 12 mm, have been widely used in electronics, acoustic products, and micro-motor. Preparing these magnets by the traditional sintering and bonding techniques is associated with complicated process and sacrificed density and machineability of the magnet. Aiming at the huge market requirements and facing those technical problems, the...
First version of relativistic BWO with TM02 operating mode has been tested also in [1]. The cyclotron-resonance mode selection was used. In this case, because of requirement to the defined values of magnetic field and e-beam radius, the efficiency of oscillator was not very high (approximately 10%). Now, the different electrodynamic codes are available to optimize the geometry of Slow Wave Structure...
The hydrodynamic, heat and mass transfer characteristics of a pressurized co‐current gas‐solid magnetically fluidized bed (MFB) were systematically investigated considering major influence factors, such as magnetic field strength, superficial gas velocity, and operating pressure. It was shown that this pressurized gas‐solid MFB has the advantages of a wider operation range of the superficial gas velocity...
