The colloidal stability of suspensions of hematite/yttria core/shell particles is investigated in this work and compared with that of the pure hematite cores. The different electrical surface characteristics of yttrium and iron oxides, as well as the diameters of both types of spherical particles, d

The effect of the shell thickness and density on the magnetic properties of composite colloidal particles consisting of a hematite (alpha-Fe(2)O(3)) core and an yttrium oxide (Y(2)O(3)) layer is described. Pure iron oxide colloidal spheres show two clearly different trends of variation of their magn
