Figure 4

Magnetotransport measurements for the MnGe nanodot arrays. (a) the temperature-dependent resistivity (lnρ versus T -1) and the inset displays the plot of lnρ versus T -1/4. (b) Temperature-dependent MR under fixed magnetic fields of 5 and 10 Tesla and the inset showing the plot of ln(MR) vs T -1/3. (c) Positive MRs at different temperatures and different magnetic fields.
