Abstract

Kikoin and Lasarew1 found that both the magnitude of R, the Hall coefficient at room temperature and its product with the conductivity, σ , at room temperature, are in general smaller for superconductors than for nonsuperconductors. Figure 1a* shows on a pair of logarithmic scales the value of the quantity R σ (which provided the better correlation) in the case of elements with normal (R < 0) and anomalous Hall coefficients (R > 0). Superconductors are listed to the left of the scale while nonsuperconductors are listed to the right.
