We have computationally studied the properties of higher-order magnetic anisotropy constants in an $L{1}_{0}/A1\text{\ensuremath{-}}\mathrm{FePt}$ core-shell system which is characterized by a strong second-order two-ion Fe-Pt component. show that structure induces unexpected fourth-order constant ${K}_{2}$, magnitude varies nonmonotonically with core-size ratio $R$ reaching peak at $R\ensurema...
Implantable biosensors were developed for real-time monitoring of pressure and strain in the human body. The sensor, which was wireless and passive, consisted of a soft magnetic material and a permanent magnet. When exposed to a low frequency AC magnetic field, the soft magnetic material generated secondary magnetic fields that also included the higher-order harmonic modes. Parameters of intere...
Recycling and reusing of catalyst is an important factor to produce capable and low cast catalysts. Silica coated magnetic nanoparticles (Fe3O4/SiO2) were synthesized via a simple sol-gel method with the aid of sonication. Fe3O4 nanoparticles. After that a layer of TiO2 was constricted by hydrolyze and condensation of Teteranormalbuthyltitanate to produce Fe3O4/SiO2/TiO2 nanocompsite. As-synthe...
Silk cocoon membrane (SCM), a solid matrix of protein fiber, responds to light, heat and moisture and converts these energies to electrical signals. Essentially it exhibits photo-electric and thermo-electric properties; making it a natural electro-magnetic sensor, which may influence the pupal development. This raises the question: 'is it only electricity?', or 'it also posses some kind of magn...
Inverted soft/hard, in contrast to conventional hard/soft, bi-magnetic core/shell nanoparticles of Mn(x)Fe(3-x)O(4)/Fe(x)Mn(3-x)O(4) with two different core sizes (7.5 and 11.5 nm) and fixed shell thickness (∼0.6 nm) have been synthesized. The structural characterization suggests that the particles have an interface with a graded composition. The magnetic characterization confirms the inverted ...
