Edwin Hall zeigte 1879, dass daf\u00fcr ein senkrecht stehendes Feld n\u00f6tig sei \u2013 ein Prinzip, das seither in Sensoren und in der Materialanalyse genutzt wird. Das Team um Simranjeet Singh und Jyoti Katoch baute atomar d\u00fcnne Schichtstapel aus dem Quantenmaterial Tantal-Iridium-Tellurid (TaIrTe\u2084) und der magnetischen Verbindung Chrom-Germanium-Tellurid (Cr\u2082Ge\u2082Te\u2086). Darin lie\u00df sich ein anomaler Hall-Effekt auch mit einem Feld parallel zur Materialebene messen.
