The ingots of Pr0.15TbxDy0.85-xFe2 (x=0.100.85) series compounds with a single phase were prepared by a arc melting method. The X-ray diffraction patterns were
A cross-linkable fluorinated poly (ether ether ketone) (FPEEK) was synthesized for the fabrication of arrayed waveguide grating (AWG) multiplexer. The results o
