Annotatsiya
Ushbu ishda oldindan sintez qilingan va mexanik faollashtirilgan kukunlardan olingan ikki komponentli kompozitlarning (1-x)PbFe₁₂O₁₉ – xPbTiO₃ ning strukturaviy xususiyatlari va fizikaviy xususiyatlarini oʻrganish natijalari keltirilgan. Kompozitlarning fizik xususiyatlarini boshqarish uchun, dopant konsentratsiyasini 0.2 dan 0.8 gacha 0.2 qadam bilan oʻzgartirishdan tashqari, mexanik faollashtirish (nanostrukturalash) usuli qoʻllanildi. Bu usul kukunga Bridjmen anvillari yordamida kuch qoʻllashni, shuningdek, aylanuvchi pastki anvil tomonidan yaratilgan siljish deformatsiyasini oʻz ichiga oladi. Rentgen difraktometriya usuli yordamida x = 0.4 bilan boshlang‘ich tarkibda dopant panjarasi parametrlarining keskin kamayishi va mexanik faollashtirishdan soʻng olti burchakli panjara parametrlarining shunga oʻxshash keskin oʻzgarishi aniqlangan.
