Two-dimensional bipolar magnetic semiconductor Cr(pyrazine)2 with high Curie-temperature and electrically controllable spin polarization

Caption

On the left, a strong d-p direct exchange magnetic interaction exists between Cr cations and pyrazine radicals. In the center, the Curie temperature Tc is displayed. On the right shows that the Cr(pyrazine)2 monolayer is an intrinsic bipolar magnetic semiconductor where electrical doping can induce half-metallic conduction with controllable spin-polarization direction.
