Abstract

with an incorrect figure. Figure 4 has been replaced as of 2 June 2016. The figure is incorrect in the printed version of the journal; therefore for the benefit of the print readership, the figure and its caption are replicated below. FIG. 4. Schematic illustration of the growth of discontinuous to continuous NM capping layer. (a) Experimental damping data for Co/Pt and Co/Au as a function of t NM. The circular point is a literature value for pure cobalt. (b) Theoretical variation in damping data for Co/Pt and Co/Au adapted from Ref. [3] as a function of t NM .

Spin current propagation through ultra-thin insulating layers in multilayered ferromagnetic systems

“…As a function of SiO 2 thickness the extrinsic contribution increases in a single large step with the thinnest oxide layer and then decreases as the thickness increases further, this decrease is comparable with the form of the scattering length density. The extrinsic contribution provides evidence further supporting the interpretation of the nominal thickness dependence as a consequence of the presence of a discontinuous insulating layer, as it has been previously shown that discontinuous coverage of a ferromagnet with a heavy metal layer leads to enhanced extrinsic damping 21 .…”

“…Spin pumping and d − d hybridization across a FM/NM interface both lead to additional magnetic energy loss and increased precessional damping. An increase in damping linked to spin pumping across a continuous insulating layer implies some form of spin current tunneling, however, even small discontinuities, such as pinholes, within the insulating layer can allow for d −d hybridization between the ferromagnetic and heavy metal layers, leading to an increase in the damping 20,21 , and limited channels for spin current propagation. A detailed understanding of the role of structure at the 2 This is the author's peer reviewed, accepted manuscript.…”

Study of spin pumping in Co thin film vis-à-vis seed and capping layers using ferromagnetic resonance spectroscopy

“…It can be seen from the Table III that the value of α for S5 and S6 is nearly equal to the bulk value of Co i.e. 0.011 [26]. It is noted that Cu has low spin orbit coupling having large spin diffusion length.…”

“…The g-factor has been calculated from the gyromagnetic ratio value. It is known that the value of H 0 depends on the quality of the thin film [25,26].…”

Spin transport and dynamics in all-oxide perovskite La2/3Sr1/3MnO3/SrRuO3

“…This is in contrast with the pronounced interfacial effect in ferromagnet/Pt bilayers 48,49 , in which even <1 nm of Pt can increase α by as much as a factor of ≈2 (Refs. [50][51][52]. In the following analysis and discussion, we show that spin pumping alone is sufficient for explaining the enhanced damping in LSMO with an SRO overlayer.…”
