Abstract: Single crystals of a new silver and-cobalt based vanadate AgCo2V3O10 were grown from a melted mixture. The crystal structure determination reveals that this new vanadate crystallizes in triclinic system with space group P (1) over bar. The structure of the filed compound is constructed from CoO6 octahedra and VO4 tetrahedra sharing edges and vertices leading to an open three-dimensional framework delimiting tunnels along [0 0 1], where the Ag cations are located. The bands observed in Raman spectrum were assigned to corresponding vibrations of the VO4 groups. DC and AC magnetization (susceptibility) measurements revealed the spin-glass (SG) - type transition below a frequency-dependent temperature T-f(H) that is nearly independent on the applied magnetic field. Magnetic field H gt; 10 kOe induces the spin glass-antiferromagnet. These observations brings AgCo2 V3O10 into the class of geometrically frustrated magnetic systems.
