Description
Summary:	In this work, the structural, magnetic, thermal, and transport properties of the arc-melted polycrystalline Heusler alloy Co2Ti1.5Sn0.5 are investigated. The alloy crystallizes in an L21 structure with a space group of Fm-3m. The magnetic properties of the alloy depict its antiferromagnetic nature and the alloy exhibits magnetic ordering around Neel Temperature TN = 8.5 K. The effective magnetic moment value obtained from the Curie –Weiss law suggests that the cobalt atom in the alloy is in the low-spin state. From the heat capacity studies, the Sommerfeld coefficient and Debye temperature were determined. In addition, electrical resistivity shows a linear response with increasing temperature, indicating the metallic nature of the alloy.
