- W109818210 abstract "The exceptionally high carrier mobilities found in zero-gap ${mathrm{Hg}}_{1ensuremath{-}x}{mathrm{Cd}}_{x}mathrm{Te}$ $(xensuremath{approx}0.10)$ give rise to giant magnetoresistance (GMR). A two-carrier, high-field model provides a good description of the magnetoresistance and Hall effect at temperatures $6<T<300$ K and magnetic fields up to $H=10$ T. The high-field data have a significant influence on the interpretation of the low-field results, in particular revealing the presence of acceptors despite the fact that the low-field Hall coefficient is negative. Surprisingly, at low fields the curvature of the GMR, ${d}^{2}{R/dH}^{2}$, is larger than that expected by up to a factor 30. The enhancement of the GMR makes ${mathrm{Hg}}_{1ensuremath{-}x}{mathrm{Cd}}_{x}mathrm{Te}$ potentially useful for read-head devices for magnetic media." @default.
