Abstract The discovery of magnetism at the LaAlO/SrTiO heterostructures has attracted a lot of interests in regards to the origin of magnetic properties appearing in this nonmagnetic system. In this paper, the existence of a robust ferromagnetic state in the LaAlO/SrTiO heterostructures is demonstrated. The oxygen vacancy dependence of magnetic phenomena demonstrates the correlation between the magnetic properties and the oxygen vacancies. The strong ferromagnetism can be also manipulated by controlling the partial pressure of oxygen during the film deposition process. The well-controlled magnetism may open an avenue for the applications of magnetic storage and spintronics with the LaAlO/SrTiO heterostructures.
