You idiot, look at Fig. 1 in Ref. 19 better and you will see that the Probe
Pulse doesn't go through the Sample, so 800 nm radiation should never make
it there, especially if one places a 800 nm Optical Rejection filter in the
path! :)
... Table II is still puzzling with respect to the flip between Ni/Ag -
Ni/Al Attenuation and Co/Ag - Co/Al Attenuation. Somehow, I would expect
the Ni Values to be correct and the Co ones to be the ones out of place...
Here are some crude e1/e2 Optical Constants I dug up, at the 0.75 THz Region
(25 cm-1 (wavenumbers), or 400 um):
Ni: e1: -6E4 e2: 3E5
Au: e1: -8.6E4 e2: 6.2E5
Ag: e1: -3E5 e2: 1.5E6
Al: e1: -3E4 e2: 1E6
where e = e1 + i e2 .
... I'm still searching for the Co Values...
FYI: Here is a link to their earlier PRL Paper when they first introduced
their Spintronic-Plasmonic Cobalt Media:
http://www.physics.gla.ac.uk/~dtngo/Article/PRL_98_133901_2007.pdf
The above paper mentions Co: e1: -1E5 .
... Have fun, Spintronicating!
