Spintronics and Non-Volatile Memory
Spintronics focus on the study of electron spin to achieve efficient information storage and computation. Compared with the traditional charge-based devices, spintronic devices are nonvolatile and consume less power. The recent development of spintronics has greatly boosted the study of post-Moore devices. For example, the magnetic random access memory (MRAM) is a new type of nonvolatile memory. Its high read-write speed and large storage capacity make it promising in replacing DRAM and SRAM, thus achieving a universal storage architecture. In addition, spintronic devices can be used to mimic the biological neurons, which could pave the way towards the next generation bio-inspired computing. PMICC focus on the key problems in spintronics. Our research topics ranging from new materials (e.g., strong spin-orbit coupling materials, ferrimagnets, antiferromagnets), novel devices (e.g., MRAM bit cell, spintronic oscillator), and critical circuits. Through these studies, we wish to advance the development of next generation storage and computing technologies in China.
