abstract = {Using low-temperature electrical measurements, the
interrelation between electron transport, magnetic
properties, and ionic defect structure in complex oxide
interface systems is investigated, focusing on NdGaO3/SrTiO3
(100) interfaces. Field-dependent Hall characteristics
(2–300 K) are obtained for samples grown at various growth
pressures. In addition to multiple electron transport,
interfacial magnetism is tracked exploiting the anomalous
Hall effect (AHE). These two properties both contribute to a
nonlinearity in the field dependence of the Hall resistance,
with multiple carrier conduction evident below 30 K and AHE
at temperatures ≲10 K. Considering these two sources
of nonlinearity, we suggest a phenomenological model
capturing the complex field dependence of the Hall
characteristics in the low-temperature regime. Our model
allows the extraction of the conventional transport
parameters and a qualitative analysis of the magnetization.
The electron mobility is found to decrease systematically
with increasing growth pressure. This suggests dominant
electron scattering by acceptor-type strontium vacancies
incorporated during growth. The AHE scales with growth
pressure. The most pronounced AHE is found at increased
growth pressure and, thus, in the most defective,
low-mobility samples, indicating a correlation between
transport, magnetism, and cation defect concentration},
