FIG. 1.

(Color online) In-plane hysteresis loops for BFO (15 nm)/CoFeB (4 nm) sample (a) measured at Tmes = 300 K and (b) at Tmes = 2 K after the specific field cooling procedure from several Ta.

FIG. 2.

(Color online) (a) Dependence of HE on Ta for BFO (tBFO)/CoFeB (4 nm) with tBFO = 15 and 70 nm. The dashed horizontal lines represent the extremum values for HE. The arrows represent the orientation of BFO pinned uncompensated spins at different Ta. (b) Dependence on Ta of the derivative of normalized HE: δHE/δTa. δHE/δTa vs Ta represents the blocking temperature distribution.

FIG. 3.

(Color online) Dependence of HE on Ta measured along the anisotropy axis for (a) BFO (250 nm)/[Co (0.4 nm)/Pt (1.8 nm)]×4 with out-of-plane anisotropy and for (b) BFO (250 nm)/Co (3 nm) with in-plane anisotropy. The insets are hysteresis loops measured at Tmes = 300 K along the deposition field axis. (c) Dependences on Ta of the derivatives of normalized HE: δHE/δTa.
