The Effects of Cu Addition in Fe-Based FeCoNiBSiNb and Co- Based CoFeNiBSiNb Glassy Ribbons on Magnetocaloric Measurements and Magnetoresistance

Öz

In this research, the effects of Cu addition which ranges from 0 % to 1 % to Fe-based Fe_0.402Co_0.201Ni_0.067B_0.227Si_0.053Nb_0.05 and Co-based Co_0.402Fe_0.201Ni_0.067B_0.227Si_0.053Nb_0.05 glassy ribbons obtained by melt spinning method on magnetocaloric and magnetoresistance properties were investigated.  In this regard, structural analyzes of the samples were evaluated by XRD, thermal properties were analyzed by DSC measurements, Curie temperatures were obtained from dM/dT vs temperature curves, magnetic properties were determined by using M-H and M-T measurements, magnetic entropy changes depending on temperature were used to determine magnetocaloric properties of the samples. In addition to these, the temperature dependent magnetoresistances were measured and the effects of adding Cu element to the composition on magnetoresistance properties were investigated. As a result, it has been concluded that the appropriate addition of Cu (about 0.75 %) on Fe- or Co-based metallic glasses enhances magnetocaloric properties and the proposed composition can probably be used for magnetic refrigeration at high temperatures.

Bu çalışmada eriyik eğirme yöntemiyle üretilmiş Fe-tabanlı Fe_0,402Co_0,201Ni_0,067B_0,227Si_0,053Nb_0,05 ve Co-tabanlı Co_0,402Fe_0,201Ni_0,067B_0,227Si_0,053Nb_0,05 amorf şeritlere % 0 ile % 1 arasında değişen oranlarda ilave edilen Cu elementinin manyetokalorik özellikler ile manyetik direnç üzerine etkisi araştırılmıştır. Bu çerçevede numunelerin yapısal analizleri XRD, ısıl analizleri DSC ölçümleriyle, Curie sıcaklıkları dM/dT - sıcaklık eğrileriyle, manyetik özellikler M-H ve M-T ölçümleriyle belirlenmiş, manyetik entropi değişimi ile sıcaklık arasındaki ilişki yardımıyla örneklerin sahip oldukları manyetokalorik özellikler belirlenmiştir. Bunlara ilave olarak, sıcaklığa bağlı manyetik direnç ölçümleri gerçekleştirilerek kompozisyona Cu elementi eklenmesinin manyetik dirence olan etkileri araştırılmıştır. Bu çalışmanın sonucunda, Fe- ve Co-tabanlı metalik cam şeritlerde tüm kompozisyona uygun miktarda (yaklaşık % 0,75) Cu ilavesinin manyetokalorik özellikleri önemli ölçüde geliştirdiği görülmüş ve teklif edilen kompozisyonun yüksek sıcaklıklarda manyetik soğutma amacıyla kullanılabileceği değerlendirilmiştir.
