## Description

- description: "Ferromagnetic semiconductors, coupling charge transport and magnetism
    via electrical means, show great promise for spin-based logic devices. Despite
    decades of efforts to achieve such co-functionality, maintaining ferromagnetic
    order at room temperature remains elusive. Here, we address this long-standing
    challenge by implanting dilute Co atoms into few-layer black phosphorus through
    atomically-thin boron nitride diffusion barrier. Our Co-doped black phosphorus-based
    lateral devices exhibit ferromagnetism up to room temperature while preserving
    its high mobility (~ \U0001D7CF\U0001D7CE\U0001D7CE\U0001D7CE \U0001D41C\U0001D426\U0001D7D0\U0001D415−\U0001D7CF\U0001D42C−\U0001D7CF)
    and semiconducting characteristics. By incorporating ferromagnetic Co-doped black
    phosphorus into magnetic tunnel junction devices, we demonstrate a highly magnetoresistance
    response that extends up to room temperature. This study presents a new approach
    to engineer ferromagnetic ordering in otherwise nonmagnetic materials, thereby
    expanding the repertoire and applications of magnetic semiconductors envisioned
    thus far."
