B. Wuyts et al., RELATION BETWEEN THE HALL ANGLE SLOPE AND THE CARRIER DENSITY IN OXYGEN-DEPLETED YBA2CU3OX FILMS, Physica. C, Superconductivity, 222(3-4), 1994, pp. 341-348
A detailed study of the Hall angle cot theta(H) in YBa2Cu3Ox epitaxial
thin films with various oxygen contents clearly shows the existence o
f a linear relation between the slope of cot theta(H) versus T2 and th
e carrier density. The zero-temperature intercept C=cot theta(H)(T=0 K
) and the mobility at room temperature change substantially for an oxy
gen content x congruent-to 6.6, indicating that both effects are close
ly related.
