Magnetic ordering in a quasi-one-dimensional S= 1/2 chain compound AgCuVO4
Here we propose to investigate the low-temperature magnetic structure of a quasi-one-dimensional S = 1/2 chain compound AgCuVO4. In contrast to typical cuprate spin-chain systems, AgCuVO4 exhibits a Cu-O-Cu bonding angle that is between the common 90° and 180°values, leading to ferro- and antiferro-magneitc interactions, respectively. Moreover, DFT calculations imply additional frustrated interchain interactions, which promise a rich magnetic phase diagram consisting of complex magnetic phase that may exhibit intriguing magnetic excitations. The system orders below TN = 2.5 K, yet its ground state is still unknown.
