While studying superconductivity in polycrystalline boron doped diamond with hydrogen covered grains, researchers of the QMAGNA team observed the coexistence of ferromagnetism and superconductivity, two usually antagonistic phenomena. Moreover, they discovered the presence of localized Cooper pairs in isolated submicron sized diamond grains. These new results were published this year in two papers in a prestigious scientific journal [G. Zhang, T. Samuely et al., ACS Nano 11 5358 (2017) and G. Zhang, T. Samuely et al., ACS Nano 11 11746 (2017)] with impact factor 14.

Polycrystalline boron doped diamond with hydrogen covered grains is both ferromagnetic and superconducting at the same time.
In the polycrystalline boron doped diamond, a phase-coherent superconducting condensate is present. In isolated nanograins localized Cooper pairs were observed.
