  The electronic structure, Fermi surface, angle dependence of the cyclotron
masses and extremal cross sections of the Fermi surface, phonon spectra,
electron-phonon Eliashberg and transport spectral functions, temperature
dependence of electrical resistivity of the HfB2 diboride were investigated
from first principles using the fully relativistic and full potential linear
muffin-tin orbital methods. The calculations of the dynamic matrix were carried
out within the framework of the linear response theory. A good agreement with
experimental data of electron-phonon spectral functions, electrical
resistivity, cyclotron masses and extremal cross sections of the Fermi surface
was achieved.
