Abstract

The magnetic structure of the spin-chain antiferromagnet  SrCo2V2O8 is determined by single-crystal neutron diffraction experiment. The system undergoes a long-range magnetic order below the critical temperature TN=4.96 K. The moment of 2.16μB per Co at 1.6K in the screw chain running along the C axis alternates in the c axis. The moments of neighboring screw chains are arranged antiferromagnetically along one in-plane axis and ferromagnetically along the other in-plane axis. This magnetic configuration breaks the four-fold symmetry of the tetragonal crystal structure and leads to two equally populated magnetic twins with the antiferromagnetic vector in the a or b axis. The very similar magnetic state to the isostructural BaCo2V2O8 warrants  SrCo2V2Oas another interesting half-integer spin-chain antiferromagnet for investigation on quantum antiferromagnetism.
