Abstract
We studied the magnetic properties of nanosized Ba2Mg2Fe12O22 powder obtained by citrate auto-combustion synthesis. The powder consists of agglomerates with mean crystallite size of 100 nm. The magnetic properties of the powder were investigated at 4.2 K and at room temperature. The values measured of the magnetization M at a magnetic field of 60 kOe are 22.78 emu/g and 30.47 emu/g at room temperature and 4.2 K, respectively. The magnetic phase transition at 183 K is related to the ferromagnetic-to-spiral spin order and is a precondition for this material’s exhibiting multiferroic properties.
