Magnetotransport effects in polar versus non-polar SrTiO3 based heterostructures
E. Flekser, M. Ben Shalom, M. Kim +4
Anisotropic magnetoresistance and negative magnetoresistance for in-plane fields are compared for the LaAlO3 /SrTiO3 interface and the symmetric Nb-doped SrTiO3 heterostructure. Bo…
Metal-to-insulator transition in anatase TiO2 thin films induced by growth rate modulation
T. Tachikawa, M. Minohara, Y. Nakanishi +5
We demonstrate control of the carrier density of single phase anatase TiO2 thin films by nearly two orders of magnitude by modulating the growth kinetics during pulsed laser deposi…
Critical thickness for ferromagnetism in LaAlO3/SrTiO3 heterostructures
Beena Kalisky, Julie A. Bert, Brannon B. Klopfer +6
In heterostructures of LaAlO3 (LAO) and SrTiO3 (STO), two nonmagnetic insulators, various forms of magnetism have been observed [1-7], which may [8, 9] or may not [10] arise from i…
