Abstract
The effect of hydrogenation from the gas phase on the change in the character of the temperature dependence of the electrical resistivity ρ(T) in the range of 77–300 K and the temperatures of phase magnetic transformations (Curie temperature TC and Néel temperature TN) of dysprosium was studied. It follows from the experimental data and their analysis that, within the framework of the indirect exchange ideas, the decreases in TC, TN and the contribution to ρ(T) related to electron scattering in the paramagnetic phase are interrelated. It has been suggested that hydrogenation effects may be related to changes in microscopic parameters: a decrease in the density of states at the Fermi level, an increase in the Fermi energy, and a decrease in the effective mass of carriers and the s-f exchange parameter.
期刊介绍：
Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies.
Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
