Magnetic properties and electronic structures of compounds from the Hf-Co phase system

Magnetic measurements of molar susceptibilities as a function of temperature in the temperature range between 5 and 400 K were performed for the intermetallic compounds Hf2Co and HfCo2, using a SQUID magnetometer. The density of states at the Fermi level for Hf2Co was evaluated from the measured spin paramagnetic susceptibility. In addition, band structure calculations using the augmented plane waves plus local orbitals (APW+1o) method as implemented in the WIEN2k programme package for the two compounds were done. The obtained results were compared with the measured data
