研究发现，对快淬非晶薄带进行退火处理，可以得到含有Sm 5 Fe 17相的Sm-Fe合金。与Nd 5 Fe 17相不同，Sm 5 Fe 17相为亚稳相。热磁研究表明Sm 5 Fe 17相的居里温度为550 K。退火后的熔纺薄带在室温下具有2.9MAm− 1的高矫顽力，在4K下具有5.0MAm− 1的高矫顽力。
It was found that Sm–Fe alloys with the Sm5Fe17phase can be obtained by annealing of the amorphous melt-spun ribbon. Unlike the Nd5Fe17phase, the hard magnetic Sm5Fe17phase was found to be the metastable phase. Thermomagnetic studies revealed the Curie temperature of the Sm5Fe17phase to be 550K. The resultant annealed melt-spun ribbon exhibited a large coercivity value of 2.9MAm−1at room temperature and 5.0MAm−1at 4K.
