  The research into insulating ferrimagnetic garnets has gained enormous
momentum in the past decade. This is partly due to the improvement in the
techniques to grow high-quality ultrathin films with desirable properties and
the advances in understanding the spin transport within the ferrimagnetic
garnets and through their interfaces with conducting materials. In recent
years, we have seen remarkable progress in controlling the magnetization state
of ferrimagnetic garnets by electrical means in suitable heterostructures and
device architectures. These advances have readily placed ferrimagnetic garnets
in a favorable position for the future development of insulating spintronic
concepts. The purpose of this article is to review recent experimental results
of the current-induced magnetization control and associated phenomena in
ferrimagnetic garnets, as well as to discuss future directions in this rapidly
evolving area of spintronics.
