    Magnetic and Microstructural Aspects of the Bulk Metallic Glassy Materials Nd60Fe30Al10

    The ferromagnetic bulk metallic glass (BMG) Nd60Fe30Al10system exhibits extremely large coercivities at low temperature and moderate coercivities near room temperature. The magnetic hardness, as best evidenced by...

    Effects of Quenching Environment on the Structure of Melt- Spun Nd2Fe14B

    Melt-spun Nd2Fe14B (2-14-1) ribbons were produced under active vacuum and different partial pressures of inert gases of Ar and He. Microstructure and thermal analyses were performed to understand the microstructu...

    Chemical Ordering and Microstructural Affects on Magnetic Properties of Sm2Fe17 and Sm2Fe17Nx

    The effect of chemical order and defect structure on the magnetization process in Sm2Fe17 and Sm2Fe17Nx has been investigated. In Sm2Fe17, chemical disorder results in the development of random anisotropy and a s...

    Effects of oxygen partial pressure on the crystallization of amorphous Bi–Sr–Ca–Cu–O and Bi–Sr–Ca–Cu–O + Ag

    The temperatures and pathways of crystallization for amorphous Bi–Sr–Ca–Cu–O are strongly dependent on oxygen partial pressure (Po2), the oxidation state of the glass, and the presence of Ag. Reducing the Po2 fro...

    Recrystallization of Amorphous or Nanocrystalline NdBa2Cu3O7-x and GdBa2Cu3O7-x

    Using a novel melt-spinning technique, we have produced highly disordered NdBa2Cu3O7-x and GdBa2Cu3Oy-x materials. Samples which were melt-spun in an O2 environment consist of nanocrystals with the tetragonal REB...

    Melt-spin processing of YBa2Cu3O7−x

    We introduce a novel containerless melt-spin processing technique for YBa2Cu3O7−x using prereacted oxide powders that are rapidly melted and subsequentially quenched in a controlled atmosphere. This results in fl...
