Two Best Power Awards at the International Conference on Magnetism

Post date: Oct. 4, 2018

I have received the Best Poster Award for my work on "Role of dimensional crossover on spin-orbit torque efficiency in magnetic insulator thin films". Thanks for the nomination of the session chair, Xuepeng Qiu, and support from other sessions chairs.

This work describes the how spin-orbit torque in the heavy metal/magnetic insulator bilayer scales with the magnetic insulator thickness. We found that the spin-orbit torque efficiency increases with the magnetic insulator TmIG thickness due to enhanced exchange interaction between heavy metal W and TmIG. Further, we demonstrated energy efficient switching in the W/TmIG with a switching current lower than that in the Pt/TmIG thanks to the large spin Hall angle in the W. This work has been published in the Nature Communications, see: https://www.nature.com/articles/s41467-018-06059-7.

I have also received the Best Poster Award for my work on "Anomalous Hall effect as an electric probe for ferrimagnetic insulator-based spintronic devices" on another day. Thanks for the nomination of the session chair, Justin Watts, and support from other sessions chairs.
