“…However, polycrystalline films of these materials have relatively low induced magnetic anisotropy [4], which is the reason for high magnetic hysteresis. This issue can be solved by introduction of an additional exchange coupled antiferromagnetic [12] of ferromagnetic [13] layer -the source of unidirectional magnetic anisotropy. The presence of the strong exchange coupling was demonstrated to effect strongly both magnetic anisotropy and hysteresis properties of the ferromagnetic layer [13].…”

The presence of the strong exchange coupling was demonstrated to effect strongly both magnetic anisotropy and hysteresis properties of the ferromagnetic layer [13]. In this work, elastomagnetoresistive properties of Fe 10 Ni 90 and Co 20 Ni 80 free layers as well as FeMn/Fe 10 Ni 90 and FeMn/Co 20 Ni 80 with unidirectional anisotropy were investigated.…”

Magnetoresistive properties of 3d-metals alloys magnetostrictive films under application of elastic deformations were investigated. Linear stress was shown to have a significant effect on magnetoresistive effect in the films through the rotation of the easy magnetization axis. Dependencies of the relative change of resistivity were obtained in a cyclic deformation regime for films of different compositions.

“…The compounds with almost equal magnetizations of sub-lattices at a given temperature and high perpendicular anisotropy are of particular interest for MRAM spintronic applications [10,11]. It is well known, that TbCo and TbFe layers with perpendicular anisotropy can be used to induce exchange bias in the adjoining hard or soft magnetic material in both out-of-plane [11,12] and in-plane directions [13,14].…”

Hysteresis properties and magnetization reversal in TbCo(30 nm) and FeNi(10 nm)/TbCo(30 nm) films with nanoscale antidot lattices are investigated to test the effect of nanoholes on the perpendicular anisotropy in the TbCo layer and the induced exchange bias in the FeNi layer. The antidots are introduced by depositing the films on top of hexagonally ordered porous anodic alumina substrates with pore diameter and interpore distance fixed to 75 nm and 105 nm, respectively. The analysis of combined vibrating sample magnetometry, Kerr microscopy and magnetic force microscopy imaging measurements has allowed us to link macroscopic and local magnetization reversal processes. For magnetically hard TbCo films, we demonstrate the tunability of magnetic anisotropy and coercive field (i.e., it increases from 0.2 T for the continuous film to 0.5 T for the antidot film). For the antidot FeNi/TbCo film, magnetization of FeNi is confirmed to be in plane. Although an exchange bias has been locally detected in the FeNi layer, the integrated hysteresis loop has increased coercivity and zero shift along the field axis due to the significantly decreased magnetic anisotropy of TbCo layer.
