In the world of materials science, sometimes main discoveries can be found in unexpected places. While working on the resistivity of a type of delafossite—PdCoO2—researchers at EPFL’s Laboratory of Quantum Materials discovered that the electrons in their sample did not behave entirely as expected. When a magnetic field was applied, the electrons retained signatures of their wave-like nature, which could be observed even under relatively high temperature conditions and appeared in relatively large sizes. These surprising results, obtained in collaboration with several research institutions, could prove useful, for example in the quest for quantum computing. The research will be published today in the prestigious journal Science.
