Abstract:
The cooperative phenomena revealed in the field and temperature dependences of the magnetization in a system of iron nanoparticles in carbon nanotubes were studied experimentally. The character of the temperature dependences of the magnetization indicates that the ferromagnetic Fe particles in carbon nanotubes are exchange-coupled. In the region where the magnetization approaches saturation, the magnetization curves reveal the power dependence $\Delta M\sim H^{-3/2}$ typical for a one-dimensional system of exchange-coupled ferromagnetic nanoparticles.
