Talk:Magneto-optic Kerr effect

Can anybody provide an estimate of the order of magnitude of the rotation of the plane of polarisation due to the magneto-optic Kerr effect? A calculation using the Faraday effect equation, Δθ=VBL gives an answer of 2 x 10^-6 degrees, which seems too small to measure, so it would be useful to know if there is a different equation which yields a larger and more realistic seeming order of magnitude for the rotation.

Also, should a table detailing the Verdet constants of certain common materials used for measuring MOKE, such as TGG, YIG, cobalt and nickel ferrite, be added to the page? In my experience, this information is very difficult to find elsewhere on the internet.

Can anybody recommend any books with detailed information on the MOKE? Ro234 10:43, 13 November 2006 (UTC)[reply]

reflectivity[edit]

The article mentions the "reflectivity of light" - this doesn't seem to make any sense - surfaces have reflectivity, not light. —Preceding unsigned comment added by 24.28.74.115 (talk) 10:06, 4 April 2010 (UTC)[reply]

light[edit]

Why is light a link in this article? This seems like a case of overlinking. --Jaapkroe (talk) 13:22, 12 February 2013 (UTC)[reply]

Only the first usage is linked, which seems reasonable to me as some people might want to read up on the electromagnetic nature of light. However, if you feel differently you are of course welcome to edit the article and delink it yourself. a13ean (talk) 15:02, 12 February 2013 (UTC)[reply]

Magneto-optic Kerr Effect vs Magneto-optical Kerr Effect?[edit]

I have seen both in use and remember at University being taught 'Magneto-optical Kerr Effect' only. I can't help but feeling that both may be acceptable but then Magneto-Optical disks are never that I'm aware of referred to as 'Magneto-optic' discs. I don't think it can be a US/UK difference as articles on both sides of the Atlantic refer to both terms. It is an effect of Magneto-optics, but both optical and optic are adjectives whilst optic is also sometimes a noun - the adjective is being used here. Optical to me sounds better as the Hard C on Optic and the hard K on Kerr otherwise run together when said quickly to 'Optiker' which rather ruins the importance of John Kerr and his wonderful effect. Not saying it needs to change the whole article but possibly list both usages, plenty of references out there for each. 150.143.118.245 (talk) 22:39, 28 November 2019 (UTC)[reply]
