| dc.description | We report on high-field magnetic properties of the silver vanadium phosphate Ag<sub>2</sub>VOP<sub>2</sub>O<sub>7</sub>. This compound has a layered crystal structure, but the specific topology of the V-P-O framework gives rise to a one-dimensional spin system, a frustrated alternating chain. Low-field magnetization measurements and band structure calculations show that Ag<sub>2</sub>VOP<sub>2</sub>O<sub>7</sub> is close to the dimer limit with the largest nearest-neighbor interaction of about 30 K. High- field magnetization data reveal the critical fields μ<sub>0</sub>H<sub>c1</sub> ≊ 23 T (closing of the spin gap) and μ<sub>0</sub>H<sub>c2</sub> ≊ 30 T (saturation by full alignment of the magnetic moments). From H<sub>c1</sub> to H<sub>c2</sub> the magnetization increases sharply similar to the system of isolated dimers. Thus, the magnetic frustration in Ag<sub>2</sub>VOP<sub>2</sub>O<sub>7</sub> bears little influence on the high-field properties of this compound. |
