Abstract

Large single crystals of the new compound SrMn $_2$ V $_2$ O $_8$ have been grown by the floating-zone method. This transition-metal based oxide is isostructural to SrNi $_2$ V $_2$ O $_8$ , described by the tetragonal space group $I4_1cd$ . Magnetic properties were investigated by means of susceptibility, magnetization, and specific heat measurements. The title compound behaves like a one-dimensional 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.
