A method for the determination of saturation magnetization of grain-oriented silicon steel sheets using the super-conducting magnet and the magnet field measurement instrument is suggested. An example is also given to illustrate the method.
Magnetic iron oxide nanoparticles have attracted broad interests in many biomedical areas, such as magnetic resonance imaging (MRI) contrast enhancement, magnetic hyperthermia, magnetic bio-sensing, and cell labeling [1]. To avoid nanoparticle aggregation and enhance their colloidal stability, carboxylate surfactants are widely used as coating materials to form steric repulsions between nanoparticles...
Magnetic property of nanoparticles is intimately related with their structure, size, morphology, and magnetic anisotropy. In recent years, some non-spherical iron oxide nanoparticles are found to have superior performance in biomedical applications compared to their spherical counterparts. For example, iron oxide nanocubes was reported to have higher magnetic heating efficiency in hyper-thermia, and...
Ferromagnetic electrodes with perpendicular magnetic anisotropy (PMA) have been extensively studied because of the outstanding performance in applications. [1] To obtain high tunneling magnetoresistance (TMR), researchers have put efforts to realize PMA with Co-based full-Heusler alloy films with MgO barrier. However, the lattice mismatch between MgO and full-Heusler alloy leads to a rapid TMR reduction...
Planar switched reluctance motors (PSRMs) have the merits of simple structure, low cost, low heat loss, high precision, ease of manufacture, and strong adaptability of harsh environment, which directly transform the mechanical energy to electromagnetic energy available to planar motions without mechanical transmissions. Therefore, PSRMs are an attractive candidate in high-precision two-dimensional...
