Özet
Ferrit seramikleri nispeten düşük maliyetli, üretilmesi kolay, mükemmel korozyon ve demanyetizasyon direnci özelliklerinden dolayı en yaygın kullanılan kalıcı mıknatıs malzemeleridir.
Abstract
Ferrite ceramics are the most commonly used permanent magnet materials becausecomparatively low-cost, easy to produce, excellent corrosion and demagnetization resistanceproperties. Ferrite ceramics are utilized in the medical devices, magnetic therapy, magnetic toys,speakers, microphones, audio systems, permanent magnetic actuators, watt-hour meters, sensors, cellphones, electric motors, etc. In this study, mass attenuation coefficients, molecular cross sections,atomic cross sections, electronic cross sections, effective atomic numbers and effective electrondensities were investigated in the energy range from 1 keV to 100 GeV for BaFe12O19, SrFe12O19,Y3Fe5O12, LiFeO2. The changes in the absorption parameters were interpreted with the photoelectriceffect, Compton scattering and pair production processes.
