"hybrid molecular beam epitaxy method used for growing metallic but nonmagnetic ultra-thin RuO2 layers, then applying epitaxial strain inducing altermagnetic state, which includes anomalous Hall effect but without having to use extreme magnetic fields to create it... magnetic effects in films just two-unit cells thick (less than a billionth of a meter)., and despite being so thin, the material remained highly metallic and structurally stable. AI, quantum computing, spintronics, low-power electronics"
