Low-temperature electronic transport in ferromagnetic cluster embedded carbon nanotubes

We present the electronic transport properties of ferromagnetic material embedded alumina template grown carbon nanotubes. Zero-field temperature dependence of the conductance in ferromagnetic cluster-embedded tubes (FM-MWNT) reveals a L\"{u}ttinger liquid type of behavior in the higher temperature region. Differential conductance measurements for discrete applied magnetic field show the appearance of field-dependent oscillations at low temperatures. The properties of the FM-MWNT were found to change permanently under the application of a magnetic field, indicating that the charge transport is sensitive to the relative magnetic orientations (random or aligned) of the nanoclusters. Those measurements suggest differences between charge transport in a L\"{u}ttinger liquid under the influence of ``random'' and ``ferromagnetically aligned'' impurities.
