An Investigation of the Magnetostriction Constant of MnCu Alloys

Bu araştırmada, % 50 den az Mn içeren MnCu alaşımlarının elastik vibrasyonundaki enerji dağılım mekanizmaları ve özellikleri incelenmiş ve bunun kristal ve manyetik yapısı ile ilişkileri incelenmiştir. Bulunan magnetostriction sabitinin (?=4×104), tipik demirmanyetik malzemelerinin karakteristiklerine göre daha yüksek olduğu bulunmuştur.

MnCu alaşımlarının manyetostriksiyon sabitlerinin incelenmesi

The properties and mechanism of energy dissipation of elastic vibrations MnCu alloys containing less than 50% Mn and its relationship between the crystal and magnetic structures are investigated. It is obtained that the magnetostriction constant, ?=4×104, is found higher than the corresponding characteristic of thypical ferromagnetic material.
