Charge neutrality in epitaxial graphene on 6 H -SiC(0001) via nitrogen intercalation
CAFFREY, NUALA (2015) -
Coexistance of Giant Tunneling Electroresistance and Magnetoresistance in an All-Oxide Composite Magnetic Tunnel Junction
SANVITO, STEFANO; RUNGGER, IVAN; CAFFREY, NUALA (2012)We propose, by performing advanced ab initio electron transport calculations, an all-oxide composite magnetic tunnel junction, within which both large tunneling magnetoresistance (TMR) and tunneling electroresistance ... -
Distance- and spin-resolved spectroscopy of iridium atoms on an iron bilayer
CAFFREY, NUALA (2016) -
Electronic properties of bulk and thin film SrRuO3: a search for the metal-insulator transition.
SANVITO, STEFANO; CAFFREY, NUALA; CAFFREY, NUALA (2008)We calculate the properties of the 4d ferromagnet SrRuO3 in bulk and thin film form with the aim of understanding the experimentally observed metal-to-insulator transition at reduced thickness. Although the spatial extent ... -
Prediction of large bias-dependent magnetoresistance in al l-oxide magnetic tunnel junctions with a ferroelectric barrier
SANVITO, STEFANO; CAFFREY, NUALA; ARCHER, THOMAS; RUNGGER, IVAN (2011)All-oxide magnetic tunnel junctions (MTJs) incorporating functional materials as insulating barriers have the potential of becoming the founding technology for novel multifunctional devices. We investigate, by first-principles ... -
Spin-filtering efficiency of ferrimagnetic spinels CoFe2O4 and NiFe2O4
SANVITO, STEFANO; CAFFREY, NUALA (2013)We assess the potential of the ferrimagnetic spinel ferrites CoFe 2 O 4 and NiFe 2 O 4 to act as spin filtering barriers in magnetic tunnel junctions. Our study is based on the electronic structure calculated by ... -
