Popis:	The present paper reports on a study of the magnetic anisotropy of the Co-based chain molecular magnet CoCu(opba)(DMSO)3. The magnetic anisotropy measurements were performed on microgram monocrystalline samples using a cantilever magnetometer at low temperatures down to 1.5 K and magnetic fields up to 7 T. The field dependence of the magnetic torque confirms an ordered ferrimagnetic structure at low temperature, T C =6 K , with a very small coercive field. Magnetic torque measurements as a function of the angle within the a–c and b–c planes suggest the emergence of biaxial behavior at low temperatures. Our results suggest that the resulting ferromagnetic moment lies perpendicular to both the CuCo-chains and hard magnetic axis.
