Professor KIM KeeHoon Develops Magnet Which Changes Poles by Electric Field
June 25, 2014 Professor KIM KeeHoon (Department of Physics and Astronomy) has developed a magnet which can change poles without the help of a magnetic field. Magnetic materials, which are a key component in hard disks, record information by changing poles using magnetic fields. This caused a problem as heat loss from electric currents to create a magnetic field was great. Professor Kim replaced the iron in hexafferite with aluminum, thus creating magnetoeletric hexafferite, and succeeded in changing magnetic poles using only electric voltage. “By changing poles with voltage and not electric currents, we can create ultra-low power magnetic elements,” said Professor Kim. This development was published in the June 24 online edition of Nature Communications. more
