Magnetic Quantum Oscillations in Nanowires

Magnetic quantum oscillations in nanowires.

Analytical expressions for the magnetization and the longitudinal conductivity of nanowires are derived in a magnetic field, B. We show that the interplay between size and magnetic field energy-level quantizations manifests itself through novel magnetic quantum oscillations in metallic nanowires. There are three characteristic frequencies of de Haas-van Alphen (dHvA) and Shubnikov-de Haas (SdH)...

Magnetic Properties of Ni0.3Fe0.7 Alloy Nanowires

The effect of length variation on the magnetic properties of NiFe alloy nanowires electrodeposited into the alumina template was investigated. The diameter (45±2.5 nm) and length (~ 1.9, 7.12, 8.3, 9.5 and 13.3 µm) of the nanowires were estimated from scanning electron microscopy images. Energy dispersive spectroscopy results showed Ni3Fe7 composition of the alloy nanowire...

Thermopower of quantum nanowires in a magnetic field.

Thermoelectric properties of nanowires in a magnetic field are studied. Magnetic splitting of thermopower peaks associated with electronic energy levels that are degenerate at zero field, leading to the development of separate thermopower peaks at larger fields, are predicted. A scheme is described for measuring thermopower in a circuit containing a nanowire and leads made from the same materia...
