Abstract
Development in bulk amorphous alloys is reviewed. R-Fe Al and R-Fe-Ga series and derivatives, of the ferrous system showing (7H)max Of 10 to 20 k.1/m3 at room temperature comparable to those of the well known rareearth (R) magnets of RZFel4B and similar intermetaliics have been dealt with along with suitable formalism for the high values. Methods of synthesis of bulk amorphous structure like rapid quenching, mechanical milling, arc melting, copper mould casting and water quenching have also been discussed.
