## Description

- description: Mn4N films with a maximum degree of order of nitrogen (S) were fabricated
    under three different substrate temperatures (Tsub), and the dominant factors
    were investigated for tuning the magnetic coercivity (Hc) in the films. It was
    revealed that Hc was strongly modulated from 10 kOe to 7.5 kOe for Tsub from 400
    to 500 degree C, whereas the S, perpendicular magnetic anisotropy (PMA), and transport
    properties did not change. The number of dislocations and in-plane grain size
    (D) increased, whereas the residual strain decreased with increasing Tsub. Thus,
    we concluded that the Hc of the Mn4N film with maximum S is sensitive to the variation
    in dislocations, which are modulated by Tsub. Because Hc is linked to thermal
    stability and working power consumption, tunable Hc is an attractive phenomenon
    from the perspective of magnetic and spintronic devices using ferrimagnetic Mn4N
    films with high PMA and low saturation magnetization.
