dc.description.abstractEnWe present thermodynamic and neutron scattering data on silver ferrite AgFeO<sub>2</sub>. The data imply that strong magnetic frustration Θ/<i>T</i><sub>N</sub>~10 and magnetic ordering arise via two successive phase transitions at <i>T</i><sub>2</sub> = 7 K and <i>T</i><sub>1</sub> = 16 K. At <i>T</i><<i>T</i><sub>2</sub>, two metamagnetic phase transitions at <i>B</i><sub>1</sub>~14 T and <i>B</i><sub>2</sub>~30 T can be identified through the change of slope in the magnetization curve measured up to 53 T. These transitions roughly correspond to an eighth and a quarter of the saturation magnetizations. Unlike for the 'classical' delafossite CuFeO<sub>2</sub>, the wavevector of the magnetic structure is independent of temperature both at <i>T</i><<i>T</i><sub>2</sub> and at <i>T</i><sub>2</sub><<i>T</i><<i>T</i><sub>1</sub>.
