Si se puede manipular con luz en tiempos ínfimos y sin recalentar el material, se abre la puerta a dispositivos de almacenamiento más rápidos y que gasten menos energía. Para quien usa computadoras y celulares todos los días, eso podría significar aparatos más veloces y menos calientes en el futuro, aunque todavía falta mucho para llegar a un producto comercial.","quienFirma":"Phys.org","confianza":"divulgacion","consulta":null},"sello":{"hash":"3ca7fb3988a702a8e5dc8516bb4fb36c3f37f9e4a9f28180f8b297519f501e20","sello":"085f693ec8ed4cd6149b0c5522a15c5d2134db192b161ba306fe074895f67bdc","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6572450,"aleatorio":"be1b8ecef4a75e4391b35bfeb6330fddf8016d260a349a4cf70b7a6fdbc47e55","tiempo":"2026-10-21T17:42:00.000Z"},"nist":{"cadena":2,"pulso":1993430,"salida":"043D402463EDFA563D513ED7AD8A82C3566D8B5A3950CAEC937A8B2EC12069C2F75066FC292C424D8119C8240F0BF7A93D5CDE733A7CED6EBF2B4E2A1CC7E5C5","tiempo":"2026-10-21T17:41:00.000Z"},"noAntes":"2026-10-21T17:42:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 17:42:24 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Ultrafast light can control ferromagnetism without relying on heating","descripcion":"Despite being known for more mundane uses such as sticking notes to refrigerators or keeping bags shut, magnetization is one of the most fundamental and useful properties of a material.
