Karazin popup.description2 The Study of the Hafnium Heat and electrical Conductivity at low Temperatures. The Objects of study: Hafnium of the "nuclear" purities. The Purpose of work: The Study of particularities of processes of carrying the heat and charge in pure hafnium in broad temperature interval. The Methods of study: The Analysis of the temperature dependencies of electrical resistivity and heat conductivity in the interval 2-300 K. It is established that at Т>150 K the electrical resistivity of the pure hafnium deviates from the usual linear temperature dependency upwards, and the heat conductivity decreases monotonous with growing of the temperature without the saturation up to the most of the high from explored temperature. The Lorentz number under specified temperature exceeds noticeably the Sommerfeld value. All these particularities is connected with the form of density of electronic state curve near the Farm level in the presence of s-d scattering.
