Abstract

We report bulk superconductivity in ZrVGe with T-c = 6 K determined by magnetization, electronic transport and specific heat measurements. From the analysis of magnetization and resistivity data we obtain the thermodynamic critical fields mu H-0(c1) and mu H-0(c2), respectively. The heat capacity data deviate from conventional BCS theory suggesting possible unconventional superconducting behavior. (C) 2015 Elsevier B.V. All rights reserved. (AU)
