説明
<jats:title>All-optical magnetic state switching</jats:title> <jats:p> Magneto-optical memory storage media, such as hard drives, use magnetic fields to change the magnetization of memory bits, but the process is slow. Light can often reveal information about the magnetization state of a sample, such as its field direction. Lambert <jats:italic>et al.</jats:italic> show that under the right circumstances, light can also switch the magnetization state of a thin ferromagnetic film. Using light pulses instead of magnetic fields led to ultrafast data memory and data storage. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6202" page="1337" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1253493">1337</jats:related-article> </jats:p>
