Ferrite ceramics are the most commonly used permanent magnet materials because

comparatively low-cost, easy to produce, excellent corrosion and demagnetization resistance

properties. Ferrite ceramics are utilized in the medical devices, magnetic therapy, magnetic toys,

speakers, microphones, audio systems, permanent magnetic actuators, watt-hour meters, sensors, cell

phones, electric motors, etc. In this study, mass attenuation coefficients, molecular cross sections,

atomic cross sections, electronic cross sections, effective atomic numbers and effective electron

densities 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 photoelectric

effect, Compton scattering and pair production processes.

Öz

Ferrit seramikleri nispeten düşük maliyetli, üretilmesi kolay, mükemmel korozyon ve demanyetizasyon direnci özelliklerinden dolayı en yaygın kullanılan kalıcı mıknatıs malzemeleridir.

Ferrit seramikler tıbbi cihazlarda, manyetik terapide, manyetik oyuncaklarda, hoparlörlerde, mikrofonlarda, ses sistemlerinde, kalıcı manyetik aktüatörlerde, watt-saat metrelerde, sensörlerde, cep

telefonlarında, elektrik motorlarında, vb. kullanılırlar. Bu çalışmada 1 keV ile 100 GeV enerji aralığında BaFe12O19, SrFe12O19, Y3Fe5O12, LiFeO2 için kütle soğurma katsayıları, moleküler tesir

kesitleri, atomik tesir kesitleri, elektronik tesir kesitleri, etkin atom numaraları ve etkin elektron yoğunlukları incelenmiştir. Soğurma parametrelerinin değişimi fotoelektrik etki, Compton saçılması ve

çift oluşum süreçleriyle yorumlanmıştır.
