Congratulations to Kai, who has successfully defended his PhD thesis on August 23. He is the first student in our group to get the PhD degree within four years right after his/her undergraduate study. 

Kai is an amazing student for our group and for the U. He has published 15 papers, one book chapter and one patent during his entire phd study, with him as the first author for 11 papers. More importantly, the quality of his papers is extremely high. Some of his papers will be seminal in his research field. Congrats again, Dr. Wu.

Congratulations to Kai Wu and co-workers! Their joint work “Characterizing Physical Properties of Superparamagnetic Nanoparticles in Liquid Phase Using Brownian Relaxation” published in Small was selected as Back Cover in volume 13, issue 22 (Small 22/2017).

The nonlinear magnetic response of SPIONs to magnetic fields induces harmonic signals that contain information of these nanoparticles. In this paper, Kai Wu, Jian-Ping Wang and co-workers, report using the phase lag and harmonic ratios in the SPIONs to analyze the saturation magnetization, average hydrodynamic size, the dominating relaxation processes of SPIONs, and the distinction between single- and multi-core particles.

Jun-Yang Chen and co-workers have created a magnetic tunnel junction (MTJ) that can be switched by a pulse of light lasting one trillionth of a second, setting a speed record. The magnetic tunnel junction is a device critical to information technology with the termination of Moore’s law, a principle that has ruled the microelectronics industry for five decades.

This advancement holds promise for the development of new, optically controlled, ultrafast magnetic devices collectively called spintronics (electronics that combine optical and magnetic nanotechnologies). These devices could lead to innovations in the storage, processing, and communication of information in the coming decade. An example of such innovation would be the development of a system that like the human brain, can both store and analyze a large amount of data simultaneously.

The details of the device and the tests conducted on it are reported in the paper “All-Optical Switching of Magnetic Tunnel Junctions with Single Subpicosecond Laser Pulses,” published in Physical Review Applied (volume 7, issue 3).

This breakthrough news is also covered by Phys.org, ScienceNewsline, and EE Times Asia.

Prof. Jian-Ping Wang has been appointed to the newly established Hartmann Chair in Electrical and Computer Engineering. The Hartmann chair was established by a generous gift from Robert F. Hartmannn who received his B.S. degree in Electrical Engineering from the University of Minnesota in 1965 and went on to found Altera Corporation in 1983.
