Аннотация:Dependences of the electrical resistivity on hydrostatic pressure (up to 10**9 Pa) at room temperature are investigated. The dependences of the exchange integral and effective mass of conduction of electrons on atomic volume are calculated from experimental data on the basis of the indirect exchange theory. The discovered anomalous behavior of those dependences when terbium is replaced by yttrium is explained by rearrangement of the electronic structure in the yttrium concentration range from 10 to 40 at. %.
