2017年1月15日 · The magnetic properties of a series of IrMn (Ir35 Mn 65)/permalloy (Ni 80 Fe 20) exchange-biased films are investigated using X-ray magnetic circular dichroism (XMCD). The ferromagnetic permalloy films in different samples are of the same thickness (5 nm) while the antiferromagnetic IrMn films have various thickness between 15 and 40 nm.

2020年11月30日 · Experimental results from PNR and XMCD indicate that a small net magnetization exists at the IrMn interface, comprised primarily of rotatable uncompensated Mn spins and a much smaller fraction...

2025年3月1日 · In this study, we employed PNR and complementary methods (XMCD, magnetometry, and mass spectrometry) to conduct a detailed examination of the structural and magnetic changes of such widely used in industry materials as antiferromagnetic IrMn 3, ferromagnetic Co, Fe and their alloy.

n conclusion, we have studied annealing process in IrMn/FM (FM=Co, Fe, CoFe) structures using PNR, XMCD, magnetometry, and SNMS. Experiments have shown that samples with Co and CoFe layers are quite resistant to annealing up to 300°C – we have not observed se

2020年9月30日 · Using high-spatial-resolution x-ray magnetic circular dichroism photoemission electron microscopy (XMCD-PEEM), we observed the imprinted spin textures within the IrMn from the XMCD signal of the uncompensated Mn spins at the interface with the ferromagnet.

Abstract: Exchange biased (EB) antiferromagnetic (AFM) - ferromagnetic (FM) bilayers are essential parts of modern spintronic devices, such as spin valve sensors or magnetic random …

2017年4月5日 · XMCD provides a unique probe for the valency determination of the constituents in ternary oxides, the depth and field profiling of magnetic constituents, magnetic origin determination in dilute magnetic semiconductors, and the study of electron correlation effects in the electronic structure.

Here we show the imprint from ferromagnetic skyrmions into a thin film of an IrMn antiferromagnet, at room temperature and zero external magnetic field, using exchange-bias. Using the high-spatial-resolution magnetic microscopy technique XMCD-PEEM, we observed the imprinted spin textures within the IrMn from the XMCD signal of the

stract. In this work, we studied the influence of the buffer layer composition on the IrMn thickness threshold for the onset of exchange bias in IrM. /Co bilayers. By means of magnetometry, x-ray absorption and x-ray photoelectron spectroscopy, .
