Easy axis demagnetizing curve and recoil loops measured at for the (a) and (b) samples. The inset shows normalized remanence curves.
(Color online) Element-specific recoil loops from the and samples at . The dotted vertical lines indicate the initial field for each recoil curve. The major demagnetization curves (with circle symbol) are shown as a reference. Normalized remanence curves from the Fe and Sm recoil curves are shown as insets.
(Color online) (a) Model structure containing three weak Sm–Co grains marked in gray. [(b)–(f)] Simulated magnetic configurations at different fields as indicated in (g). (g) Simulated recoil loops for the total, Fe and Sm–Co layers.
