| Description
| - Nanosized gama-Fe2O3 is one of the most remarkable iron(III) oxide polymorph with extensive applications in praktice. However, its exploitation in nanosized form is limited by presence of parasitic magnetic phenomena emerging if the size of gama-Fe2O3 nanoobjects falls below a certain threshold value. One of them is a spin canting negatively reflecting in a capability of these nanoobjects to be easily controlled by an external magnetic field. Knowledge of all parameters affecting spin canting may shed light into understanding of this parasitic phenomenon, thus enabling its prevention. For a study of spin canting, in-field 57Fe Mössbauer spectroscopy is widely recognized as the most powerful experimental tool allowing qualitative and quantitative determination of the degree of this phenomenon. In this work, we study the parameters having an impact on spin canting phenomenon occurring in the two gama-Fe2O3 nanoparticle systems exhibiting different average particle size and particle size distribution. It turns out that the spin canting phenomenon significantly depends on the temperature and its thermal evolution is influenced by average particle size and particle size distribution of a gama-Fe2O3 nanoparticle assembly. For smaller nanoparticles, diminishing of spin canting is assisted by collective magnetic excitations. Moreover, we propose a statistically-based procedure testing the nature and site-occurrence of spin canting phenomenon in the studied gama-Fe2O3 nanoparticle systems.
