Metal-Insulater Transition

  1. May 24, 2007 #1
    Dear everydody can you please help me to understand how can by heating your sample they jumb from Insulater state to an metal state when we rich to a certain value of temperature for exemple the Rare earth Nickelate compounds.

    Best regard

    If you are refering to the perovskite nickelates (RNiO3), I can tell you that about 10 years ago, it was believed that (I think in at least some of the compounds) the transition was associated with a weak Jahn-Teller distortion. I've not followed up since then.

    Unfortunately, that's the crux of what I recall.

    I think I might be able to dig up some papers on this though...but then, that's probably something that you can do as well as me.
