We present the synthesis and study of the magnetic and electronic properties of NiFe2O4/{\gamma}-Al2O3/SrTiO3 heterostructure. The {\gamma}-Al2O3/SrTiO3 interface hosts a high-mobility two-dimensional electron gas (2DEG) with large…

Ferroelectric and ferromagnetic orders rarely coexist, and magnetoelectric coupling is even more scarce. A possible avenue for combining these orders is by interface design, where orders formed at the constituent materials can overlap and…
