The study investigates the magnetic effects at the interface between nonmagnetic oxides, specifically SrTiO$_3$ and LaAlO$_3$. The researchers found that this interface can induce a highly conductive and magnetically active region, characterized by a large negative magnetoresistance and a logarithmic temperature dependence of the sheet resistance. At low temperatures, the sheet resistance exhibits magnetic hysteresis, suggesting the presence of magnetic ordering. The interface's magnetism is attributed to the interplay between localized magnetic moments and itinerant conduction electrons, potentially involving the Kondo effect. The findings highlight the potential of oxide interfaces as versatile systems for inducing and manipulating magnetic moments in nonmagnetic materials, opening new avenues for carrier-controlled ferromagnetism in all-oxide devices.The study investigates the magnetic effects at the interface between nonmagnetic oxides, specifically SrTiO$_3$ and LaAlO$_3$.
