Show affiliationsA glassy composite magnetic wire was prepared by elongation during quenching phase-separated melt in two-liquids stable immiscibility region of Fe3O4-TiO2-SiO2 ternary system. The glass-ceramics in the Fe3O4-TiO2-SiO2 system has a phase-separation texture, which consisted of Fe3O4-TiO2-rich and SiO2-rich phases, and shows ferromagnetic properties. The internal textures of wire samples were needle-like structure parallel to the direction of the elongation. The wire sample had larger saturated magnetization and lower coercive force than those of non-elongated bulk one.
