Growth and magnetic properties of MnCl2-4SC(NH2)2 single crystals
Abstract
NiCl2-4SC(NH2)2 (DTN) is a famous one-dimensional antiferromagnet with magnon Bose-Einstein condensation. In this work, single crystals of MnCl2-4SC(NH2)2 (DTM) with size up to (8-10)×(8-10)×(3-5) mm3 are grown by using the slow evaporation method with optimized conditions. The single crystals are characterized by measurements of X-ray diffraction, magnetic susceptibility, and specific heat. It is found that although DTM has a similar crystal structure to DTN, it shows a paramagnetic behavior. The reason for no spin exchange among Mn2+ ions can be understood in terms of the negligible overlap of the Mn2+-3d orbital and the neighboring Cl--3p orbital.
