The Ids–Vg characteristics of the aluminum-oxide glassy alloy ( Ni 0.36 Nb 0.24 Zr 0.40)90- H 10 field-effect transistor (GAFET) for gate–drain bias voltage from -50 to +50 μV were measured at room temperature. We observed four kinds of drain current oscillations for gate voltage at two-current plateau regions of -20~-15 and +35~+40 μV. The transistor showed the three-dimensional Coulomb diamond structure. From DC current standards I=ef, we get f=256 GHz for the first peak, being tunneling of one electron.

The amorphous Ni – Nb – Zr – H glassy alloy containing subnanometer-sized icosahedral Zr 5 Nb 5 Ni 3 clusters exhibited four types of electronic phenomena: a metal/insulator transition, an electric current-induced voltage oscillation (Coulomb oscillation), giant capacitor behavior and an electron avalanche with superior resistivity. These findings could be excluded by charge density waves that the low-dimensional component of clusters, in which the atoms are lined up in chains along the [130] direction, plays important roles in various electron transport phenomena.

We Successfully Prepared the Rod Glassy Samples of (Fe1-xCox)76Si9B10P5 (x = 0~0.4) Bulk Metallic Glass (BMG) with the Diameters up to 3.0 mm by Substituting Fe for a Small Amount of Co Element. A Certain Amount of Co Substitution for Fe Contributes to the Increase of the Glass-Forming Ability (GFA) while Maintaining Good Mechanical Properties (the Fracture Strength up to 3700 MPa). This Co-Added Ferromagnetic Bulk Glassy Alloy System Also Exhibits a Higher Saturation Magnetization of 1.49 T and Lower Coercive Force (Hc, 1.2 A/m). The Fe-Based BMGs with Alloying a Small Amount of Co Element Demonstrate Excellent Combination of High GFA, Good Soft-Magnetic Properties as Well as High Strength.
