Cation distribution dependent magnetic properties in CoCr 2−x Fe x O 4 (x = 0.1 to 0.5): EXAFS, Mössbauer and magnetic measurements

Evolution of structure and rich magnetic transitions such as paramagnetic to ferrimagnetic phase transition at Curie temperature ( T C ), spiral ordering temperature ( T S ) and lock-in temperature ( T L ) have been discussed in CoCr 2 O 4 spinel multiferroic after substituting Fe.
