Abstract: Mössbauer spectroscopy has been used to study maghemite ($\gamma$-Fe$_2$O$_3$) particles with average dimensions on the microscopic ($\sim$1 $\mu$m, “bulk” state) and nanoscopic (15 and 20 nm) levels. Data provided by this method on the thickness of a surface region of magnetic nanoparticles and features of their magnetic state have been analyzed. It is suggested that the proposed approach is promising for a large number of nanomagnetic materials.
