Antiferromagnetic Heisenberg S=5/2 spin chain compound SrMn${}_2$V${}_2$O${}_8$

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 $I{4}_{1}cd$. 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.
