Laser blast flips magnet’s polarity instantly without heating it up
A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...
Abstract: In this study, we investigate the magnetization process at high frequencies based on the energy landscape outputted by machine learning. Employing a combination of Topological Data Analysis ...
If a strong laser pulse hits an iron alloy, the material melts briefly at the irradiated point and a tiny magnetic area forms. Credit: HZDR / Sander Münster A research team has revealed that ...
This process is repeated several times, whereby the time interval between the first "pump" pulse and the subsequent "probe" pulse is continually extended. As a result, a time series of reflection data ...
Abstract: Artificial spin ice (ASI) consists of submicrometer-sized magnetic cells, which shows emergent behaviors of the magnetizations in the cells. To apply the magnetization dynamics of the ASI to ...
An intense laser pulse is shone onto the material, inducing ultrafast spin flipping processes that occur on a timescale of ~100 attoseconds. Credit: © J. Harms, MPSD ...
Department of Geosciences, University of Wisconsin-Milwaukee, Milwaukee, WI, United States Microbialites–layered, organosedimentary deposits–exist in the geologic record and extend back in deep time, ...
