explanation

what is meant by "s-d scattering"? - Saibod 10:04, 17 October 2007 (UTC)[reply]

The scattering of electrons in the free-electron-like 4sp band by the 3d electrons. Yes, this should be explained somewhere. /Pieter Kuiper 14:46, 17 October 2007 (UTC)[reply]

Inconsistencies

There are a couple of inconsistencies in this article.

First, under "Discovery," it is stated that the resistance decreases when the current is at 90 degrees to the magnetic force, but in the caption of the Corbino disc picture it's stated that this configuration causes an increase in the resistance.

Second, the first equation in "The Corbino disc" section gives a contribution to the velocity vector proportional to v cross B. But v cross B is perpendicular to v by definition, so using this to solve for v cannot be right unless v adjusts itself such that the E field cancels the vector component perpendicular to v itself. If this is right, it needs to be explained more clearly.
