“…The matrix phase (R 2 Fe 14 B, R = Nd, Dy) showed a Fe:R atomic ratio of about 7.2, which is a reasonable value since boron was not analyzed. Another phase in these materials showed a Fe:R atomic ratio of about 1.7 and this might be a RFe 2 phase [18]. Laves phase NbFe 2 has also been found in these materials [19][20][21][22].…”
