▎ 摘 要
NOVELTY - Ferromagnetic material comprises at least one Dirac half metal material having a Fermi velocity up to 3.83x105m/s as compared to a Fermi velocity of graphene. USE - Ferromagnetic material for heterostructure(claimed) and spintronic devices. ADVANTAGE - The ferromagnetic material exhibits 100% spin polarization, and electrons exhibit ultrahigh mobility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a spintronic device, which comprises a Dirac half metal material; and (2) a heterostructure, which comprises the ferromagnetic material.
