Development of magnetic levitation and magnetic hardness performance of Sn-Ba-Cu-O ceramics due to ZnO doping

Öz

The structural properties of Sn2Ba(Cu2-xZnx)2Oy ceramics synthesized by solid-state reaction method with different Cu/Zn doping ratios were investigated in our previous study. In this study, magnetic levitation force (MLF) measurements were performed using a permanent magnet with a surface magnetic field strength of 470 mT. In the force measurement between the magnet and the ceramic material, significant hysteresis behavior was observed statically as a function of the distance in the vertical axis. We focused on the effect of doping on force measurements and magnetic stiffness calculations under zero field cooling (ZFC) and field cooling (FC) conditions. The decrease of force with increasing doping in ZFC is explained by weak bonds at grain boundaries, cracks and grain size reduction. Magnetic stiffness calculations were made from the force curves in ZFC. The levitation force, which should be effective with the increase in doping in FC, was replaced by an attractive force with the emerge of flux trapping centers. In addition, from the 3-cycle force curves in FC, the range in which the samples are sensitive was determined as 0-35 mm. The doping caused a decrease in magnetic stiffness values. In FC, when the force curves were evaluated holistically, it was seen that the doping increased the maximum repulsive and attractive force and the repulsive force reached a maximum of 0.7 mN and the attractive force reached a maximum of 3.25 mN.

Sn-Ba-Cu-O seramiklerin manyetik kaldırma ve manyetik sertlik performansının ZnO katkılamasına bağlı gelişimi

Öz

Farklı oranlarda Cu/Zn katkılanarak katı-hal tepkime yöntemiyle sentezlenen Sn2Ba(Cu2-xZnx)2Oy seramiklerin yapısal özellikleri önceki çalışmamızda incelendi. Bu çalışmada, 470 mT yüzey manyetik alan şiddetine sahip kalıcı mıknatıs kullanılarak manyetik kaldırma kuvveti (MLF) ölçümleri gerçekleştirildi. Mıknatıs ile seramik malzeme arasındaki kuvvet ölçümünde, statik olarak düşey eksendeki mesafenin fonksiyonu olarak önemli histerezis davranış gözlendi. Sıfır alan soğutması (ZFC) ve alan soğutması (FC) şartlarında, katkılamanın kuvvet ölçümleri ve manyetik sertlik hesaplamalarına etkisine odaklanıldı. ZFC′de katkı artışıyla kuvvetin azalması, tane sınırlarındaki zayıf bağlar, çatlaklar ve tane boyutu küçülmesi ile açıklandı. ZFC′de kuvvet eğrilerinden, manyetik sertlik hesaplamaları yapıldı. FC′de katkının artması ile etkili olması gereken kaldırma kuvveti, akı yakalama merkezlerinin ortaya çıkması ile yerini çekici kuvvete bıraktı. Ayrıca, FC′de 3 döngülü kuvvet eğrilerinden, numunelerin duyarlı olduğu aralık 0-35 mm olarak belirlendi. Katkılama manyetik sertlik değerlerinde azalmaya neden oldu. FC′de, kuvvet eğrileri bütünsel değerlendirildiğinde, katkının maksimum itici ve çekici kuvveti artırdığı ve itici kuvvetin maksimum 0.7 mN′a, çekici kuvvetin ise maksimum 3.25 mN′a ulaştığı görüldü.
