Review of voltage-controlled magnetic anisotropy and magnetic insulator

This Festschrift is dedicated to Chia-Ling Chien on the occasion of his eightieth birthday. Prof. Chien is one of the pioneering physicists in the field of spintronics with groundbreaking achievements in giant magnetoresistance, proximity effects in superconductor/ferromagnet multilayers, exchange bias, spin-transfer torque effect, voltage-controlled spin mechanisms, spin-caloritronics and so on. We will focus and give a brief review on the two aspects, the voltage-controlled magnetic anisotropy (VCMA), the magnetic insulator (MI), and related works.
