dc.description.abstractε-Fe2O3 has gained considerable interest due to its intriguing properties and great application potentials. In this work ε-(Fe1−xCrx)2O3 (x = 0, 0.03, 0.075) nanoparticles encapsulated in silica have been successfully prepared by sol–gel chemistry. Synchrotron diffraction confirms that the polar Pna21 structure of ε-Fe2O3 is robust against the substitution of Fe by Cr. The incorporation of chromium is accompanied by a softer magnetic behaviour, and also a gradual decrease in the ferromagnetic signal associated to the super-hard FM2 ferrimagnetic phase. While the Cr substitution has little impact on the low temperature incommensurate transition, it is found that Cr substitution shifts the super-hard and soft ferrimagnetic transitions (respectively, TN2 and TN1) to notably lower temperatures.es_ES
