Fracture Toughness of Polycrystalline Ni-Zn Ferrite and Polycrystalline Ba Ferrite

Electric and Magnetic Properties of Ta-Doped Polycrystalline Mn-Zn Ferrite

Theeffect ofTa205additiveon the electric and magnetic properties of MnZn ferrites with fine grain size was studied Aadding small amounts ofTa205 to the MnZn ferriteincreased electric resistivity, while an excessive addition of Ta205causeddecreasein resistivity without significant grain growth. In asmall amount ofTa205 the change in the electric resistivity can be explained by ~ a ' ' substituti...

PULSED LASER DEPOSITION OF Ni-Zn FERRITE THIN FILMS

Thin Ni0.5 Zn0.5 Fe2 O4 ferrite films were grown on different condition on different substrates using pulsed laser deposition technique. Studying the influence of the energy of the laser beam, of the O2 pressure, of the substrate temperature, and of the distance between the target and the substrate on the microstructure and on the magnetic properties were established optimal conditions for PLD ...

Thick Film Ni-Ferrite Inductors

Porous Ba Ferrite Prepared from Wood Template

Ba ferrite materials with porous microstructures were prepared from a natural cedar wood template in order to investigate new electromagnetic shielding materials. The wood templates were infiltrated with barium nitrate and iron nitrate solutions (molar ratio = 1:12) and dried to form ferrite gel, then, they were sintered in air at a temperature between 800 °C and 1400 °C. The 1-dimensional poro...
