报告摘要：

Charge and spin are the two intrinsic attributes of electrons, which pave the way for electronic devices in our daily life. In this talk, I would like to focus on how the interfaces between strongly correlated oxide materials can magically modulate charge and spins of electrons, leading to various exotic physical phenomena [1,2]. Moreover, by virtue of interfacial coupling in multiferroic heterostructures, we have been able to electrically control electronic properties of intermetallic alloys, which is potential for super low energy-consuming memory applications [3-5].
