Abstract : The general object of this invention is to provide a method of directly crystallizing samples of the Sm-Fe system onto a substrate. A more particular object of the invention is to provide such a method of synthesizing a metastable phase at a composition corresponding to a (Sm + Ti) to Fe atomic ratio of 1:5. By metastable in this context is meant that the phase formed at a 1:5 atomic ratio is not present in the pure Sm-Fe system. It has now been found that the aforementioned objectives can be attained by synthesizing by selectively thermalizing sputtering onto heated substrates with the addition of Ti as a stabilizing agent. Room temperature intrinsic coercive forces of 6.2 kOe and static energy products of 5.5 MG-Oe have been obtained in this Ti stabilized (Sm + Ti):Fe 1:5 compound. (Author)
