Magnetic and SOT properties for the Ta or Pt/Nb/CoFeB/MgO/Ta films. (a, c) Effective anisotropy energy Keff and \({\xi }_{DL(FL)}\) as a function of \({t}_{Nb}\) in the Ta/Nb series. The green dots in a show the Keff of Nb/CoFeB/MgO/Ta for comparison. (b, d) Effective anisotropy energy Keff and \({\xi }_{DL(FL)}\) as a function of \({t}_{Nb}\) in the Pt/Nb series, respectively.
