Abstract:
We report the results of investigations of $\varepsilon$-Fe$_{2}$O$_{3}$ magnetic nanoparticles obtained by incipient wetness impregnation of silica gel. It was established that the obtained samples with an iron content of 12–16% mass % containing $\varepsilon$-Fe$_{2}$O$_{3}$ nanoparticles with an average size of 10 nm on the silica gel surface exhibit a room-temperature coercivity of about 10 kOe. Along with fabrication simplicity, this fact makes the prepared samples promising for application as a magnetically hard material.
