## Description

- description: The tunnel magnetoresistance (TMR) is one of the most important spintronic
    phenomena but its reduction at finite temperature is a severe drawback for applications.
    Here, we reveal a crucial determinant of the drawback, that is, the s−d exchange
    interaction between conduction s and localized d electrons at interfacial ferromagnetic
    layers. By calculating the temperature dependence of the TMR ratio in Fe/MgO/Fe(001),
    we show that the obtained TMR ratio significantly decreases with increasing temperature
    owing to the spin-flip scattering in the Δ1 state induced by the s−d exchange
    interaction. The material dependence of the coupling constant Jsd is also discussed
    on the basis of a nonempirical method.
