Abstract

In this study, thermal treatments dependence of Magneto-impedance (MI) effect in Co72.5Si12.5B15 wires has been investigated. Wires were annealed at 460 °C for different times (1- 400 min). It was found that low time annealed leads to increase in magnetic softness. The largest change in the MI was observed at 1 MHz frequency value. It was determined that maximum MI, coercivity (Hc) and maximum field sensitivity (S) values were 247%, 1.28 A/m and 1.35% per A/m respectively in the wire annealed at 460 °C for 10 minutes. This high MI and field sensitivity value occurring in low annealed time shows that this wire can be used in the design of low magnetic field sensors.

CoSiB Tellerin Manyeto-empedansında Isıl İşlem Etkisi

Abstract

Bu çalışmada Co72.5Si12.5B15 tellerde Manyeto-empedans (ME) etkinin ısıl işleme bağlılığı incelenmiştir. Numuneler 460°C’de farklı sürelerde ısıtılmıştır (1-400 dakika). Düşük süreli ısıl işlemlerin manyetik yumuşaklıkta artışa yol açtığı bulunmuştur. MI değerinde en büyük değişim 1MHz frekans değerinde gözlenmiştir. MI, Hc ve maksimum alan hassasiyet (S) değerleri 460 °C’de 10 dakika ısıl işlemde sırasıyla %247, 1.28 A/m ve A/m başına %1.35 olarak belirlenmiştir. Düşük ısıl işlem süresinde ortaya çıkan bu yüksek MI ve alan hassasiyet değeri bu telin düşük manyetik alan sensörlerinin tasarımında kullanılabileceğini göstermektedir.
