Effects of Thermomechanical Treatment on Phase Transformation of the Ti₅₀Ni₄₉W₁ Shape Memory Alloy

Metals, 2020
The Ti50Ni49W1 alloy has a B2 ↔ 19’ martensitic transformation but slightly lower shape recovery than the Ti50Ni50 alloy. The B19’ martensite structure in the Ti50Ni49W1 has the lattice parameters a = 0.301 nm; b = 0.423 nm; c = 0.472 nm; and β = 97.5 ...

Efficient Current‐Driven Perpendicular Magnetization Switching Through the Synergy of the Orbital and Spin Hall Effects

Advanced Science, EarlyView.
NiNb alloys enable efficient charge‐to‐spin conversion by combining the spin Hall effect of nickel with the orbital Hall effect of niobium. Composition tuning yields spin‐torque efficiencies of −1.4 to −1.7 and a non‐monotonic efficiency‐resistivity relationship, revealing orbital‐spin synergy beyond conventional spin Hall materials and offering a ...
