MAGNITOSTRIKSIYa

MAGNITOSTRIKSIYa (az yun. magnetis — magnit va lot. strictio — fishurdashavi, kashidashavi), tagyiri shakl va hajmi jism hangomi magnitnokshavi. Hodisai Magnitostriksiyaro Ch. Noul soli 1842 kashf kardaast. Dar ferro va ferrimagnetikho (Ee, Ni, So, Gd, Tb va g., yak qator khulaho, ferritho) buzurgii Magnitostriksiya khele kalon d/ —- g» 10—* — 10-2 meshavad. Dar antiferromagnetik va diamagnetikho Magnitostriksiya kamtar ast. Darozshavii nisbii on odatan dar samti maydoni magniti (Magnitostriksiyai qadi) yo dar samti nisbat ba samti maydon amudi (Magnitostriksiyai bari) chen karda meshavad. Hodisai aksi Magnitostriksiya— tagyiryobii magnitvokshavii namunai ferromagniti hangomi deformasiya — effekti magnitiyu chandiri yo bazan effekti Villari nomida meshavad. Magnitostriksiyaro dar tekhnika ba tavri vase istifoda mebarand.
