Nanocrystalline Nickel Ferrite, NiFe2O4: Mechanosynthesis, Nonequilibrium Cation Distribution, Canted Spin Arrangement, and Magnetic Behavior
V. Šepelák,Ingo Bergmann,Armin Feldhoff,Paul Heitjans,Frank Krumeich,Dirk Menzel,Fred Jochen Litterst,Stewart J Campbell,Klaus Becker +8 more
TL;DR: In this article, the inner core of a NiFe2O4 nanoparticle is considered to possess a fully inverse spinel structure with a Neel-type collinear spin alignment, whereas the surface shell is found to be structurally and magnetically disordered due to the nearly random distribution of cations and the canted spin arrangement.
