From: The emergence of magnetic ordering at complex oxide interfaces tuned by defects
a Comparison of the 5 K magnetic hysteresis loops of the B-site cation-deficient 9-u.c. LAO layers, grown on TiO2-terminated STO(001) and LAO(001) substrates using a low laser fluence, Eg = ~0.6 J/cm2. b Magnetization density of a tetragonally distorted LAO with a VAl. c The total spin-polarized density of states near the valence band states for the tetragonally distorted LAO with a VAl (in the left panel) and the corresponding local density of states of the neighbouring six oxygen atoms next to a VAl (in the right panel). d Laser fluence dependence of the 5 K magnetic hysteresis loops of 9-u.c. STO layers, grown on TiO2-terminated STO(001) substrates. e Magnetization density of a cubic STO with a VTi. f Total density of-states near the valence band states for the STO with a VTi (in the left panel) and the corresponding local density of states of the six neighbouring oxygen atoms next to a VTi (in the right panel).
