Therefore, the insulation coating is crucial to improve magnetic performances of SMCs by increasing electrical resistivity and reducing the eddy... design (Lake Shore 7407). AC magnetic performance (core loss and permeability measured at 50 mT was obtained by an B-H analyzer (MATS-2010SA). 3 Results and discussion Figure 2 shows the the surface......
with the magnetic domain reversal of the metal inner core. As well known, the Fe-rich microwires have a longitudinally magnetized inner core and a radially magnetized thin outer shell[14-15]. The radius... the microwave magnetic field can penetrate most of the inner metal core and consume large part of microwave magnetic energy in the measured frequency range. In the excitation of microwave......
