Effect of exchange springs on the coercivity of DyFe2-YFe2 superlattices

Effect of exchange springs on the coercivity of DyFe2-YFe2 superlattices
Effect of exchange springs on the coercivity of DyFe2-YFe2 superlattices
The coercivity of MBE-grown Laves-phase DyFe2–YFe2 thin-layered (50 Å) superlattice samples, with a (1 1 0) growth direction, can be varied by adjusting the relative thickness of the YFe2 and DyFe2 layers. However, for sufficiently thick layers, the coercivity is found to be dependent on the thickness of the YFe2 layers, even when the ratio of DyFe2/YFe2 is fixed. This feature is illustrated using the superlattice films [wDyFe2/wYFe2]×40, with w=75, 100 and 150 Å. The underlying reason for the decrease in coercivity with increasing width w, is traced to the action of the magnetic exchange springs in the YFe2 layers.

Abstract

The coercivity of MBE-grown Laves-phase DyFe2–YFe2 thin-layered (50 Å) superlattice samples, with a (1 1 0) growth direction, can be varied by adjusting the relative thickness of the YFe2 and DyFe2 layers. However, for sufficiently thick layers, the coercivity is found to be dependent on the thickness of the YFe2 layers, even when the ratio of DyFe2/YFe2 is fixed. This feature is illustrated using the superlattice films [wDyFe2/wYFe2]×40, with w=75, 100 and 150 Å. The underlying reason for the decrease in coercivity with increasing width w, is traced to the action of the magnetic exchange springs in the YFe2 layers.
