The zero-magnetization Heusler ferrimagnet
(2013)
An unusual zero-moment half-metallic state has been predicted in stoichiometric Heusler compounds with 24 valence electrons, where, unlike an antiferromagnet, the two sublattices are chemically or crystallographically ...
Controlled fabrication of nickel perpendicular nanocontacts using focused ion beam milling
(American Institute of Physics, 2006)
A method for the controlled fabrication of a nickel perpendicular nanocontact with diameters less
than 5 nm is reported. The method involves milling pores through the 100 nm thick silicon nitride
membrane using a focused ...
Z-pinch Discharge in Laser Produced Plasma
(2010)
Z-pinch effects in a laser produced aluminium plasma were investigated with a
relatively low current fast coaxial electrical discharge. The ion flux in the laser produced
plasma (LPP) was monitored with a Langmuir ion ...
Electronic spin-spin decoherence contribution in molecular qubits by quantum unitary spin dynamics
(Elsevier BV, 2019)
The realisation of quantum computers based on molecular electronic spins requires the design of qubits with very long coherence times, . Dephasing can proceed over several different microscopic pathways, active at the same ...
Ferromagnetism in defect-ridden oxides and related materials
(2010)
The existence of high-temperature ferromagnetism in thin films and nanoparticles of oxides containing small quantities of magnetic dopants remains controversial. Some regard these materials as dilute magnetic semiconductors, ...
Magnetic, magnetotransport, and optical properties of Al-doped Zn0.95Co0.05O thin films
(American Institute of Physics, 2007)
Thin films of 5% Co-doped ZnO with a range of Al codoping exhibit a band-edge shift, which varies with carrier concentration as n2/3. Carrier effective mass is 0.26me and mobility is ~ 10?cm2?V?1?s?1. The doped films, which ...
Liquid-Phase Exfoliation of Nanotubes and Graphene
(2009)
Many applications of carbon nanotubes require the exfoliation of the nanotubes to give
individual tubes in the liquid phase. This requires the dispersion, exfoliation and
stabilisation of nanotubes in a variety of liquids. ...
Large positive in-plane magnetoresistance induced by localized states at nanodomain boundaries in graphene
(2017)
Graphene supports long spin lifetimes and long diffusion lengths at room temperature, making it highly promising for spintronics. However, making graphene magnetic remains a principal challenge despite the many proposed ...
Non-Invasive Monitoring Of Chick Development In Ovo Using A 7T MRI System From Day 12 Incubation Through To Hatching
(2007)
Purpose: To determine whether mild cooling of the egg reduces movement to the point where an ultra-high-field (7T) MRI system can be used to noninvasively monitor chick growth in ovo from 12 days incubation through to ...
