A new type of low-energy magnetic semiconductor material!

A new type of magnetic semiconductor material can reduce the energy required by computers in data storage processes, and this research has broad application prospects in the development of energy-saving electronic devices.

Research has found that a new type of magnetic semiconductor material may reduce the energy consumption of computers and other electronic devices. At this year's National Sigma West Conference, this research made physicists from South Dakota State University the focus of the conference.

west gate? Gilbert tested the magnetic properties and structural characteristics of this new type of magnetic semiconductor material and found that it helps reduce the energy required for data storage in computer hard drives. This material is an alloy composed of cobalt, iron, chromium, and aluminum elements, in which a portion of the aluminum element in the structure is replaced by silicon. Currently, researchers are collaborating with the Nanomagnetism Research Group at the Nebraska Center for Materials and Nanoscience.

This research has earned Gilbert recognition in fields such as physics, astronomy, and engineering, and has been awarded the Higgs Prize for Outstanding Poster. In addition, he also accepted an invitation to join the prestigious International Society for Science and Engineering.

Computers need to operate in environments with temperatures higher than room temperature, "Gilbert said. Due to the presence of aluminum, this new type of magnetic semiconductor material can maintain its magnetic properties at 450 degrees Fahrenheit (approximately 232 ℃). Researchers have found that replacing a small portion of aluminum with silicon can further increase the operating temperature to nearly 1000 degrees Fahrenheit (approximately 538 ℃). The development of these two materials was carried out in collaboration with researchers in Nebraska.

This is a huge progress, "Gilbert said. His research advisor was Professor Rong Xu and Assistant Professor Parashu Kharel, and this study was completed with funding from the San Diego State University Excellence Research Program and the Research and Scholarship Support Fund.

When it comes to supercomputers, energy conservation is a very important issue, "Gilbert added. Researchers from San Diego State University and the University of Nebraska Lincoln will continue to develop this promising material.

I am glad that my research has been valued, "said Gilbert, who himself will receive his bachelor's degree this semester and then pursue graduate studies at the research institute.

Research experience is one of the most valuable skills that undergraduate students can acquire in the early stages of their academic careers, "Kharel said. As long as they come to our laboratory, we will do our best to help them lay the foundation for their next graduate studies or work

Xu Rong pointed out that ensuring that undergraduate students can conduct experiments is one of the advantages of the physics research program at San Diego State University. Simon's dedication in the Physical Materials and Nanoscience Laboratory led him to a higher level of research work.
