Kin Fai Mak and Jie Shan Developed a New Imaging Technique that is Fast and Sensitive Enough to Observe Two-Dimensional Magnet Fluctuations

A Cornell team developed a new imaging technique that is fast and sensitive enough to observe these elusive critical fluctuations in two-dimensional magnets. This real-time imaging allows researchers to control the fluctuations and switch magnetism via a “passive” mechanism that could eventually lead to more energy-efficient magnetic storage devices.

The team’s paper, “Imaging and Control of Critical Fluctuations in Two-Dimensional Magnets,” published June 8 in Nature Materials.

The paper’s co-senior authors are Kin Fai Mak, associate professor of physics in the College of Arts and Sciences, and Jie Shan, professor of applied and engineering physics in the College of Engineering. Both researchers are members of the Kavli Institute at Cornell for Nanoscale Science, and they came to Cornell through the provost’s Nanoscale Science and Microsystems Engineering (NEXT Nano) initiative. Their shared lab specializes in the physics of atomically thin quantum materials.
