“…It should be mentioned that in the HNiPy sample in the descending branch of the hysteresis loop, the bottom FM-layer reverses prior to the top one. This can be confirmed by the coercivities for the top and bottom subloops that correlate perfectly with the coercivities of the separate HNiPy/IrMn and IrMn/HNiPy structures [34]. However, for the LNiPy sample in the descending branch of the hysteresis loop, the top FM-layer reverses prior to the bottom one.…”

We demonstrate the magnetization reversal features in NiFe/IrMn/NiFe thin-film structures with 40% and 75% relative content of Ni in Permalloy in the temperature range from 80 K to 300 K. At the descending branches of the hysteresis loops, the magnetization reversal sequence of the two ferromagnetic layers is found to depend on the type of NiFe alloy. In the samples with 75% relative content of Ni, the bottom ferromagnetic layer reverses prior to the top one. On the contrary, in the samples with 40% of Ni, the top ferromagnetic layer reverses prior to the bottom one. These tendencies of magnetization reversal are preserved in the entire range of temperatures. These distinctions can be explained by the morphological and structural differences of interfaces in the samples based on two types of Permalloy.
