【 摘 要 】

Large single crystals of the new compound SrMn2V2O8 have been grown by the floating-zone method. This transition-metal based oxide is isostructural to SrNi2V2O8, described by the tetragonal space group I4(1)cd. Magnetic properties were investigated by means of susceptibility, magnetization, and specific-heat measurements. The compound behaves like a 1D magnetic system above the ordering temperature (T-N=43 K). The magnetic ground state can be described as a classical long-range ordered antiferromagnet with weak anisotropy. (C) 2011 Elsevier B.V. All rights reserved.
