"structural frustration at interface of 2 compounds: manganese/ cobalt/ germanium, and manganese/ cobalt/ arsenic... translates to magnetic frustration causing atomic spins to twist, creating desired magnetic properties for: high-density hard drives, reduced power consumption for data centers as moving skyrmions requires little energy, materials for fault-tolerant quantum computing"
