Magnetic Interactions at the Nanoscale in Trilayer Titanates
Magnetic Interactions at the Nanoscale in Trilayer Titanates
We report on the phase diagram of competing magnetic interactions at the nanoscale in engineered ultrathin trilayer heterostructures of ${\mathrm{LaTiO}}_{3}/{\mathrm{SrTiO}}_{3}/{\mathrm{YTiO}}_{3}$, in which the interfacial inversion symmetry is explicitly broken. Combined atomic layer resolved scanning transmission electron microscopy with electron energy loss spectroscopy and electrical transport have confirmed the formation of …
