Unification of bulk and interface electroresistive switching in oxide systems

A. Ruotolo, C. W. Leung, C. Y. Lam +3

We demonstrate that the physical mechanism behind electroresistive switching in oxide Schottky systems is electroformation, as in insulating oxides. Negative resistance shown by th…

High-quality all-oxide Schottky junctions fabricated on heavily Nb-doped SrTiO3 substrates

A. Ruotolo, C. Y. Lam, W. F. Cheng +2

We present a detailed investigation of the electrical properties of epitaxial La0.7Sr0.3MnO3/SrTi0.98Nb0.02O3 Schottky junctions. A fabrication process that allows reduction of the…

Controlling the exchange interaction using the spin-flip transition of antiferromagnetic spins in Ni $_{81}$ Fe $_{19}$ / $α$ -Fe $_{2}$ O $_{3}$

Joonghoe Dho, C. W. Leung, Z. H. Barber +1

We report studies of exchange bias and coercivity in ferromagnetic Ni $_{81}$ Fe $_{19}$ layers coupled to antiferromagnetic (AF) (0001), (11 $2 ˉ$ 0), and (11 $0 ˉ$ 2) $α$ -Fe $_{2}$ …
