Giant Thermoelectric Power in Co/Al2O3 Ferromagnetic Nanocomposites Below Percolation Threshold

“…Temperature dependence of electrical conductivity σ for FMNC with low Co content was found to follow the Mott law for electrical conductivity with variable hopping range: where e is the electron charge, R is the hopping length, ν ph is the factor of the interaction phonon spectrum, N ( E ) is the electron density of states at the Fermi level E F , d is the localization radius, k is the Boltzmann constant.…”

“…But the number of experimental researches is very restricted. [5,13,14] The behavior of thermoelectric power in magnetic field below percolation threshold in magnetic nanocomposites was not studied at all. The task of this paper is to investigate thermoelectric power dependences on a temperature in a magnetic field for FMNC's having different Co content below percolation threshold.…”

Thermoelectric coefficient of nanoscale transition metals films

“…Thermoelectric properties in island and granulated metal systems are studied in several papers, e.g. [9][10][11][12][13]. The interest in thermoelectric properties of metal nanoisland structures is due to the fact that, on the one hand, they can have a high electrical conductivity, and on the other handa low thermal conductivity.…”
