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…
