Currently, there is a challenge stumping the electronic industry with regards to energy efficiency and they believe that magnetic materials might be the answer to this problem. The benefits and uses of magnets in Brisbane are seen in various applications and fields.
Energy efficiency is believed to be the key to the future of electronics. A warning has already been released by the Semiconductor Research Corporation because of the continued increase in the demand for energy provided by electronics but they estimated that in 20 years the demand for the energy worldwide will surpass that of the entire amount generated.
Carnegie Mellon University’s assistant professor in the field of materials science and engineering, Vincent Sokalski, is currently developing a solution to the issue. He will employ magnetic materials to improve the efficiency of energy used in memory as well as computing.
Sokalski was granted a funding worth $1.8 million by the Defense Advanced Research Projects Agency (DARPA). His project is called Domain Wall Skyrmions. He is working with Di Xiao, a professor in Physics, and Marc De Graef, a professor in material science and engineering.
Currently, magnetic materials are employed in hard disk drives for the purpose of storing data in long term while semiconductors are now being utilized for processing and memory for short term use only thus the energy used is higher. The size of semiconductors continues to shrink because of the demand of the consumers for density as well as speed. The problem is that these can only get as small before it is no longer practical for risk of information loss. DARPA knows this and this is why they are looking for other measures that will upgrade the magnetic materials employed in computer memory used for both storage and processes.
The project being developed by Sokalski focuses on magnetic materials. He is hoping that in the near future semiconductors are not the only solution for computing, better yet if he could find an alternative to replace it entirely. While the materials might not be exactly the same as the magnets in Brisbane but he is starting out with he refers to as the 2D magnetic bubbles.
