Abstract

In this work, FeTe0.7Se0.3 single crystals have been synthesized by using the self-flux method, in order to understand effect of Te doping in the Fe-chalcogenides. For this purpose, the physical properties of sample have been investigated by Scanning Electron Microscopy (SEM), Energy dispersive x-ray (EDX) spectroscopy, X-ray diffraction (XRD) and magnetic techniques. The XRD results show that the sample has tetragonal structure, with some impurity peaks. SEM results demonstrate that the sample is distributed in a terrace-like formation. EDX results indicate that the distribution of Fe, Te and Se on the surface of the sample is homogenous. According to χ-1-T measurement, antiferromagnetic interaction is observed. In addition, M-H curves show nearly paramagnetic behavior for the sample measured.

Özet

Bu çalışma kapsamında, Fe-kalkojenlerin fiziksel mekanizmasını daha iyi irdelemek için FeTe0.7Se0.3 tek kristali self-flux metodu kullanılarak sentezlendi. Bu bağlamda, hazırlanan numunenin fiziksel özellikleri, Taramalı Elektron Mikroskopu (SEM), Enerji Saçılımlı X-ışını Spektroskopi (EDX), X-Işını Kırınımı (XRD) ve manyetik teknikleri kullanılarak incelendi. Numune, XRD sonucunda tetragonal kristal yapı ile birlikte bazı safsızlık piklerinin de varlığını sergilemektedir. SEM sonucu, numunenin terasa benzer bir oluşum olduğunu göstermektedir. EDS sonucu, Fe, Te ve Se elementlerinin numune yüzeyinde homojen olarak dağıldığını göstermektedir. χ-1-T ölçümlerine göre, numunede antiferromanyetik etkileşmeler gözlemlenmektedir. Buna ek olarak, M-H grafiklerinde ise neredeyse paramanyetik davranışın olduğunu göstermektedir.
