| contents | We obtain in single van-der-Waals layer of MnBi2Te4 the spin-valve-like ferromagnet/spin glass (SG)/ferromagnet architecture, where the switch of individual spin states in the SG-like layer appears as the resistance switch behavior. The characteristic temperature of SG can be effectively tuned by fine-control of Bi-doping in the SG layer. A doping- and temperature-dependent phase diagram is established. We demonstrate the remote manipulation and detection of the states of individual Mn-layer spins by tunneling electrons in favor of the electron-phonon, spin-phonon, spin-transfer torque and spin-flip interactions among hot electrons, lattice and local spins, where the spin valve layer is even buried below two-quintuple-layer Bi2Te3. The integration of the SG state into spin valves opens the opportunity of realizing atomic-scale spintronics by integrating different degrees of freedom in two dimensional materials. |
