Das am 27.

Ihre Netto-Magnetisierung ist praktisch null, wodurch sie sich kaum st\u00f6ren lassen &#8211; dennoch behandeln sie die Spin-Ausrichtung der Elektronen richtungsabh\u00e4ngig. Genau das macht sie f\u00fcr die Spintronik interessant: Diese verarbeitet Informationen nicht \u00fcber die elektrische Ladung, sondern \u00fcber den Elektronenspin und verspricht dadurch schnellere und sparsamere Bauteile als klassische Halbleiterchips.<\/p><div id=\"netgu-562735405\" class=\"netgu-content netgu-entity-placement\"><aside class=\"deals-top deals-top--compact\">\n\n\t\t\t<h3

class=\"wp-block-paragraph\">Als kompaktes Material gilt RuO&#8322; eigentlich als unmagnetisch. Erst als das Team unter Ming Yi (Erstautor Yichen Zhang) das Oxid zu einem ultrad\u00fcnnen Film wachsen und ihn epitaktisch verspannen lie\u00df, zeigte die direkte Messung der Spin-Textur die charakteristischen Muster. Ohne Gitterdehnung verschwand der Effekt. Die Verspannung lie\u00dfe sich damit wom\u00f6glich als &#8222;Regler&#8220; nutzen, um den Magnetismus gezielt ein- und auszuschalten &#8211; ein attraktiver Ansatz f\u00fcr stromsparende Speicher und Logikbausteine.<\/p>\n\n<h3 class=\"wp-block-heading\">Noch Grundlagenforschung<\/h3>\n\n<p class=\"wp-block-paragraph\">Einordnung ist wichtig: Es handelt sich um eine Labormessung an speziell pr\u00e4parierten D\u00fcnnschichten. Ob RuO&#8322; wirklich ein Altermagnet ist, wird in der Fachwelt seit Jahren kontrovers diskutiert. Die neue Arbeit liefert dazu belastbare Belege, aber keinen Schlusspunkt. Von marktreifen Chips oder Speichern ist die Forschung noch weit entfernt &#8211; sie zeigt jedoch, dass sich ein vielversprechender Quantenzustand \u00fcber eine gut kontrollierbare Stellgr\u00f6\u00dfe erzeugen l\u00e4sst.<\/p>\n\n<p class=\"wp-block-paragraph\"><em>Quellen: <\/em><a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.aec2917\" target=\"_blank\" rel=\"noopener\">Science Advances (DOI: 10.1126\/sciadv.aec2917)<\/a><em>, <\/em><a href=\"https:\/\/www.sciencedaily.com\/releases\/2026\/08\/260826055454.htm\" target=\"_blank\" rel=\"noopener\">ScienceDaily<\/a><em>, <\/em><a href=\"https:\/\/www.thebrighterside.news\/post\/ultrathin-ruthenium-dioxide-discovery-could-enable-faster-smaller-and-more-efficient-computer-devices\/\" target=\"_blank\" rel=\"noopener\">The Brighter Side of News<\/a><em>.<\/em><\/p><div id=\"netgu-2463126000\" class=\"netgu-after-content netgu-entity-placement\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-6258556257245998\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-6258556257245998\" \ndata-ad-slot=\"4559785002\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Ein hauchd\u00fcnner, mechanisch verspannter Film aus Rutheniumdioxid zeigt Altermagnetismus \u2013 eine exotische Magnetform, die stromsparende Spintronik-Chips erm\u00f6glichen k\u00f6nnte.
