Coexistence Between Superconductivity and Magnetism in Dy-doped ZrTe<sub>3</sub> single crystals

POSTER

Abstract

ZrTe3 is a well-known van der Waals chain compound with a monoclinic structure [1] which bears a remarkable coexistence between superconductivity at 2.0 K and charge density waves (CDW) at 63 K [2]. Furthermore, it has been shown that its properties may be tuned by intercalation with transition metals [3], substitution with other chalcogenides [4] or defect engineering [5]. Our preliminary crystallographic through X-ray diffractometry and chemical analysis through Energy Dispersive Spectroscopy show that it is possible to obtain high quality Dy doped ZrTe3 crystals with bulk superconductivity of possible multiband nature with Tc at 5.6 K, as observed by electrical transport measurements. We also show the development of an antiferromagnetic ordering inside the superconducting state which is confirmed by means magnetization measurements, with TN at 4.3 K.
