Ag layer thickness dependence of magnetic properties in Fe/Ag superlattices

Formation of metastable phases and their effect on the magnetic properties of Co-Cu multilayers

“…6(d), indicating an incomplete antiferromagnetic coupling between adjacent Co layers [41]. It does not saturate up to 5 kOe and shows almost no hysteresis, while the magnetization curve shows near saturation at low H. Similar behavior was observed for the Fe/Ag and other Co-Cu multilayers [4,8,12]. This gradual decrease of MR at higher H can be related to some strongly pinned domains which require much stronger field to rotate.…”

“…As a result, the low field sensitivity was elevated to 0.8%/Oe. Numerous reports of spacer effect on MR and magnetization have been presented and discussed in terms of antiferromagnetic coupling or interfacial states [4][5][6], while little discussions on influence of ferromagnetic layer [8,9] show that it has not been so extensively addressed.…”

“…The films composed of noble metals (Cu, Ag, Au) and ferromagnetic 3d transition metals (Fe, Co, Ni, or their alloys) have been studied extensively for their structural advantages such as sharp interface and consequent applications, especially in magnetoresistance (MR) [1][2][3][4][5][6][7][8][9]. For instance, with the aim of using giant magnetoresistance (GMR) devices as magnetic sensors, Hylton et al [1] first elaborated intermediate structures between multilayers and granular alloys.…”

Microstructure and Magnetic Properties of Ag/Fe/Ag Pseudo-Sandwich Nanogranular Films

“…Chemam et al reveals that magnetic properties of Fe/Ag superlattices depend on the Ag layer thickness [24]. [Fe(20Å)/Ag(t)] 20 superlattices with silver film thickness varying from 7Å to 20Å were prepared by molecular beam epitaxy on polished (001) MgO substrate.…”
