The exotic properties in strongly correlated electronic materials such as high-TC superconductivity in cuprates, colossal magnetoresistance in manganites, magnetoelectric coupling in multiferroics are intimately related to the coexistence and competition of nearly degenerate states — charge, lattice, orbital, and spin. This provides a strong motivation to explore materials or structures in which the spin degree of freedom can be manipulated using new strategies, e.g. an electrical knob, apart from traditional magnetic field. In this talk, after a short introduction of my oxide group in Beijing Normal University, I shall share some of our recent insights about spin physics in complex oxide thin films and heterostructures, covering 3d, 4d and 5d transition metal perovskite oxides. Majorly using scanning probe techniques (where local magnetism can be characterized with a spatial resolution), I would like to introduce how to design emerging correlated behaviors using epitaxial growth with an atomic precision and then control magnetism under external stimuli, which may provide a wide platform for potential next-generation spintronic devices.
