A new experimental discovery, led by researchers at the University of Minnesota, demonstrates that the chemical element ruthenium (Ru) is the fourth single element to have unique magnetic properties at room temperature. The discovery could be used to improve sensors, devices in the computer memory and logic industry, or other devices using magnetic materials.  

“Magnetism is always amazing. It proves itself again. We are excited and grateful to be the first group to experimentally demonstrate and add the fourth ferromagnetic element at room temperature to the periodic table,” said University of Minnesota Robert F. Hartmann professor of electrical and computer engineering Jian-Ping Wang, the corresponding author for the paper and Quarterman’s advisor.

In addition to Quarterman, Wang, and Voyles, researchers involved in this study include Javier Garcia-Barriocanal from the University of Minnesota Characterization Facility; Yang Lv from the University of Minnesota Department of Electrical and Computer Engineering; Mahendra DC from the University of Minnesota School of Physics and Astronomy; Sasikanth Manipatruni, Demitri Nikonov, and Ian Yang from Intel Components Research; and Congi Sun from the University of Wisconsin Department of Materials Science and Engineering.

To read the full paper entitled “Demonstration of Ru as the 4th ferromagnetic element at room temperature,” by Quarterman et al, visit the Nature Communications website.

The recent issue of Open Rivers Journal reported our research in mercury detection.

Mercury contamination has been an important environmental and health concern throughout the world for decades. High exposures to mercuric ion (Hg2+) may result in acrodynia (pink disease) and damage to the nervous system and kidneys. Furthermore, mercuric ion is stable and soluble in aquatic systems, and methyl mercury can accumulate in bodies through the food chain, which is known to cause brain damage and other chronic diseases, even paralysis and death. Nowadays, the detection of trace-level toxic heavy metal ions mostly relies on bulky and costly analytical instruments in central labs. Driven by this need, Prof. Jian-Ping Wang and his group at the University of Minnesota developed and tested a diagnostic platform designed to detect mercuric ion (Hg2+) using nanotechnology.
