Physics of Superconductivity and Magnetism

Magnetic properties of SrCo2V 2O8 single crystal are investigated by means of ac magnetic susceptibility, dc magnetization and heat capacity measurements. The results show that SrCo2V 2O8 possesses two canted antiferromagnetic transitions at ∼5 and ∼3 K, which is different from isostructural BaCo2V 2O8 with only one antiferromagnetic transition at ∼5 K. We suggest that such different magnetic properties are mainly due to their different structural symmetry.
