Oblique-angle deposition of Ta or W underlayers induces uniaxial magnetic anisotropy in CoFeB/Pt stacks, enabling deterministic field-free spin-orbit torque switching at current densities down to 2e11 A/m2.
Due to the symmetry with EA⊥σ, there is no USMR response to magnetization reversal, which compli- cates the detection of deterministic CIMS

Uniaxial Magnetic Anisotropy and Type-X/Y Current-Induced Magnetization Switching in Oblique-Angle-Deposited Ta/CoFeB/Pt and W/CoFeB/Pt Heterostructures
Oblique-angle deposition of Ta or W underlayers induces uniaxial magnetic anisotropy in CoFeB/Pt stacks, enabling deterministic field-free spin-orbit torque switching at current densities down to 2e11 A/m2.
