“…In order to search for the new class of materials, it has been found that solid solution of mixed metal oxides might be a potential candidate, having advantage of easy alloying due to ionic radius of same order [3,4]. Fe 2-x Cr x O 3 is one such compound series, which can be formed through the alloying of -Fe 2 O 3 and Cr 2 O 3 oxides [5,6]. The interesting points are that both -Fe 2 O 3 and Cr 2 O 3 stabilized into rhombohedral crystal structure with space group R3C [4,7] and both are antiferromagnetic insulator [8].…”

The compound Cr 1.4 Fe 0.6 O 3 has been synthesized through mechanical alloying of Cr 2 O 3 and -Fe 2 O 3 powders and subsequent thermal annealing. The XRD spectrum, SEM picture and microanalysis of EDAX spectrum have been used to understand the structural evolution during alloy formation. The alloyed samples have been matched to rhombohedral structure with R3C space group. The observation of a modulated magnetic order confirmed the systematic diffusion of Fe atoms into the Cr sites of lattice structure. A field induced magnetic behaviour has been noted in the field dependence of magnetization data of the annealed samples. This feature is significantly different from that of the mechanical alloyed samples. The experimental results also provided the indications of considering the present material as a potential candidate for opto-electronic applications.

“…The substitution effect in -Fe 2 O 3 at Fe site influences the electrical, magnetic and other physical  in the scientific community as the dopant like Zn ions substituting for Fe 3+ in the corundum-related structure leads to formation of cationic and anionic vacancies [2][3][4][5][6]. The effect of substitution of Cr and Mn ions in GaFeO 3 manifests itself and can be delineated starting with suitable oxide precursors preferentially containing Cr (Mn) in the Ga or Fe site.…”

“…The effect of substitution of Cr and Mn ions in GaFeO 3 manifests itself and can be delineated starting with suitable oxide precursors preferentially containing Cr (Mn) in the Ga or Fe site. It is noteworthy that Cr (Mn) substitution in the octahedral Fe (1,2) site of GaFeO 3 has marked effects on the structural parameters and magnetic properties, while substitution in the octahedral Ga 2 site has marginal effects [2][3][4][5][6][7][8].…”

“…The magnetic and structural properties of haematite are also affected by particle size [7,8], degree of crystallinity [9], pressure [10], doping [2][3][4][5][6], and mechanical alloying [11] due to its technological applications. It is noticed that depending upon milling conditions, structural phase transformations of nanostructured haematite to maghemite, magnetite and wüstite can be induced.…”
