Figure 5

Low temperature Seebeck coefficient and magnetic susceptibility of Ge0.9Bi0.1MnTe1.94Se0.06 measured with two processes of heating and cooling. (a) Low temperature Seebeck coefficient and (b) low temperature magnetic susceptibility. The insets in (a) and (b) are the difference of Seebeck coefficient and magnetic susceptibility between the cooling and heating progress, respectively.
