The Role of Frozen Spins in the Exchange Anisotropy of Core–Shell Fe@Fe(3)O(4) Nanoparticles
Core–shell Fe@Fe(3)O(4) nanoparticles exhibit substantial exchange bias at low temperatures, mediated by unidirectionally aligned moments at the core–shell interface. These spins are frozen into magnetic alignment with field cooling, and are depinned in a temperature-dependent manner. The population...
