A new discovery by physicists at Martin Luther University Halle-Wittenberg could make certain components in computers and smartphones obsolete. The team has succeeded in directly converting frequencies to higher ranges in a common magnetic material without the need for additional components. Frequency multiplication is a fundamental process in modern electronics.
The surprising effect of frequency multiplication is explained by synchronized switching of the dynamic magnetization on a micron scale."Different areas do not switch at the same time. Instead, they are triggered by adjacent areas just like in a falling row of dominoes," explains first author Chris Körner from the Institute of Physics at MLU.more energy efficient in the future. It is also important for new applications.
