Figure 10. Effect of magnetic molecular filling on the resistance of CNTs (Reproduced with permission^[14]. Copyright 2011, Springer Nature): (A) TEM of MWCNT filled with Mn₁₂Ac, scale bar is 5 nm, and schematic of magnetoresistance measurement apparatus and Mn₁₂Ac molecules filled in CNTs. (B) Magnetoresistance of Mn₁₂Ac@MWCNT (1) and the control sample of pristine MWCNT (3) at 2 K in the presence of a magnetic field (H) either perpendicular (θ = 0°) or parallel (θ = 90°) to the conducting layers. (C) Low field region of the magnetoresistance measurements.
