Electrical Behaviour of Heavy Electron Compounds

  • C. S. Sunandana

Abstract

We consider in this paper certain aspects of the electrical resistivity behaviour of selected heavy electron compounds. First we classify the compounds into two broad categories:
  1. 1.

    Compounds exhibiting convexity followed by resistivity saturation or virtually temperature independent resistivity: Np, UPt3, UIn3, USn3 also U2Ti and U3T (T = Si, Os, Ir) (to be discussed later), UPt, UCd11:

     
  2. 2.

    Phases with a negative temperature coefficient of resistivity down to low temperatures ( ∼ 50K) leading to anomalous maxima and a precipitous drop to zero/small value at subkelvin temperatures: U2Zn17, NpBe13, CeCu6, CeAl3, CeCu2Si2, CePb3 and UBe13 — in the order of increasing sharpness of the low temperature maximum.
