From: Origin of perpendicular magnetic anisotropy in amorphous thin films
(a) BH loops of Co–Zr–Ta–B thin films deposited under different argon sputtering pressure. Inset shows the easy axis hysteresis loop of the 1.6 mTorr film, (b) Zoomed-in area of the BH loops of films deposited at 1.6–4 mTorr pressure showing the evolution of perpendicular magnetic component, (c) Anisotropic filed (Hk) and coercivity (Hc) versus argon sputtering pressure for all films.
