This dataset supports the manuscipt C. Swindells, A.T. Hindmarch, A.J. Gallant and D. Atkinson, 'Spin transport across the interface in ferromagnetic/nonmagnetic systems'.

A description of the data and file formats is included below.
Please contact Aidan Hindmarch <a.t.hindmarch@durham.ac.uk> with any questions.

All data was taken using a homebuilt FMR system based on an Agilent VNA.

All files are comma delimited with further details described either as headings or below.
 
Trendlines, fits are not included, but can be reproduced from the measured data as described in the manuscript. 

Data for Figure 1a contains 161 Slices of the FMR colour plot. Each file has 3 columns for Field (Oe), Constant Frequency for the slice (GHz), and Intensty (arb.)

Data for Figure 1b contains data for an example Kittel curve (Pt [2nm]/ Co [3nm]) with Applied Field (Oe),Raw Frequency (GHz), errors in field (Oe) as the columns. The colorplot can be extracted by fixing a value for the g-factor and Meff, then calculating the Chi squared value - giving an intensity. Varying both values will give a colorplot as presented in the manuscript.

Data for Figure 1c contains the increasing in damping linewidth as detailed in the manuscript for three thicknesses of both FM and NM material for a Co/Pt system.

Data for Figure 2 containts the extracted spin mixing data for Ru for HCP and FCC Co, reduced by a factor of 10^18 for plotting purposes.

Data for Figure 3 contains the extracted spin mixing data as a function of Pt thickness for each system. Inset data can be found under 'Supplemental Figure 1'

Data for Supplemental Figure 1 contains the extracted FMR Field linewidth for various FM thicknesses (denoted by number in name of variable) as a function of Pt Thickness.

Data for Supplemental Figure 2 contains a folder with each file the results of a simulation for the spin accumulation (mu) for a given bulk diffusion length with varying boundary conditions in nm- given by the name of the file. Contained within each file are two columns - the first the thickness and the second the spin accumulation. The spin diffusion length can be found as described in the manuscript, by considering the value of 1/e for each condition.
