“…One can also use ion irradiation or ion implantation as a means of causing strain relaxation, atomic rearrangements and even demixing at interfaces. The latter was observed in MBE-grown Ag/Fe/Ag trilayers [82], where strain fields induced by depositing the film on a bent substrate were relaxed after implantation of Fe ions. In these it was observed, from measurements using FMR and XRD, that the effective in-plane anisotropy decreased linearly when the out-of-plane lattice parameter increased from 0.284 nm to 0.288 nm.…”

The magnetic ordering in transition metals is strongly affected by any strain in the lattice, due to the close connection between strain and anisotropy. This article reviews recent developments, both experimental and theoretical, in the field of strain-induced magnetic anisotropies, with focus on films and multilayers based on Fe and Co. It is demonstrated that the reorientation of preferred magnetization directions can be controlled through both the growth direction and the strain state, which is caused by interleaving with suitable spacers, as well as by tuning the chemical composition if the magnetic material is an alloy. Both inplane and out-of-plane easy directions can be forced upon the films and superlattices in this manner. Some methods for local structural manipulation are also reviewed.

We have grown by molecular beam epitaxy (MBE) 300 Å Fe films on single crystal MgO(001) substrates with Ag buffer layer with a thickness varying from 0 to 150 Å. The epitaxial growth and structure quality of the films were verified by reflection high-energy electron diffraction (RHEED) and X-ray diffraction. Small angle X-ray diffraction revealed the dependence of interfacial roughness on the thickness of Ag buffer layer. In-plane magnetic anisotropy was determined by means of magneto-optic Kerr effect at room temperature. The analysis of hysteresis loops showed a dependence of uniaxial anisotropy field H u and coercive fields on the Ag buffer layer.

Ferromagnetic resonance of dry etched permalloy thin films

et al. 1999

Permalloy thin films deposited by rf magnetron sputtering are ion beam etched or reactive ion etehed. Effects of the dry etching on magnetic properties are examined by ferromagnetic resonance and the results are shown as a function of film thickness (etching time). The perpendicular resonance field shifts toward a higher field as ion beam etching proceeds, but it moves to a lower field in the case of reactive ion etching. The effective magnetization of ion beam etched thin films is slightly increased, but the opposite behavior is observed in reactive ion etched thin films. The exchange stiffness constant decreases gradually with ion beam etching whereas a sudden drop to about 5x10' erg/cm oceurs by reactive ion etching. This result ean be explained by surface etching-damaged layer.Index Termsion beam etching, reactive ion etching, ferromagnetic resonance, permalloy, etching damage
