Growth of FeTe single crystals and investigation of their structure and magnetic properties

Abstract

In the present work, the growth of Fe1 xTe single crystals by the Bridgman method, their structure and magnetic properties are reported. The chemical composition of the Fe1.06Te crystals is determined from the X-ray diffraction pattern. The magnetic measurements reveal a phase transition from the paramagnetic into the antiferromagnetic state at 64 K. The calculated asymptotic Curie–Weiss temperature ΘCW =-203 K indicates the dominance of antiferromagnetic interactions.
