The decomposition process of the precursor amorphous phase in [formula omitted] ([formula omitted] and 3) has been studied by means of x-ray diffractometry and Mössbauer spectroscopy with particular attention paid to the formation of [formula omitted] induced by Cr. Amorphous [formula omitted] was confirmed to decompose to stable [formula omitted] via metastable [formula omitted] during isothermal annealing at 953 K. However, the metastable formation of magnetically hard [formula omitted] in the Cr-added system is spoiled by a preannealing treatment at 873 K which alters the metastable decomposition products from [formula omitted] to [formula omitted] We discuss the Cr-induced formation of [formula omitted] from the viewpoint of kinetics.
