Scholarcy highlights

  • The electrical control of two-dimensional van der Waals ferromagnets is a step forward for the realization of spintronic devices
  • The P↑ state does not change the semiconducting nature of CGT
  • Non-volatile, electrical-controlled switching of ferromagnetic CGT can be engineered by the two opposite ferroelectric states of single layer SCO
  • The magnetic easy axis of CGT switches from in-plane to out-of-plane when the direction of electric polarization of SCO is altered from P↓ to P↑
  • Nonvolatile electrical control of 2D Cr2Ge2Te6 and intrinsic half metallicity in multiferroic hetero-structures
