Tenth Young Researche<strong>rs</strong> Conference – Materials Science <strong>and</strong> Engineering<br />

Ab initio study <strong>of</strong> electronic structure <strong>and</strong> hyperfine<br />
interaction paramete<strong>rs</strong> in HfV2 <strong>and</strong> ZrV2 Laves phases<br />

Using <strong>the</strong> augmented plane wave plus local orbitals method we have performed calculations on<br />
C15 Laves phases HfV2 <strong>and</strong> ZrV2, within <strong>the</strong> framework <strong>of</strong> <strong>the</strong> density functional <strong>the</strong>ory.<br />
Optimized structure, electronic properties <strong>and</strong> electric field gradients (EFG) have been calculated.<br />
In addition, supercell calculations <strong>of</strong> hyperfine interaction paramete<strong>rs</strong> at <strong>the</strong> nucleus positions <strong>of</strong><br />
181Ta <strong>and</strong> 111Cd were also carried out. Results for EFGs were compared with <strong>the</strong> available<br />
experimental data from differential perturbed angular correlation (TDPAC) measurements in order<br />
to elucidate <strong>the</strong> role played by 181Ta <strong>and</strong> 111Cd probes in TDPAC experiments.<br />

The intermetallic compounds formed as a combination <strong>of</strong> hydride-forming <strong>and</strong> hydride-nonforming<br />
metals are <strong>the</strong> class <strong>of</strong> materials <strong>of</strong> special interest for hydrogen storage applications (solid<br />
state hydrogen storage, nickel metal-hydride batteries...). In this work, <strong>the</strong> results <strong>of</strong> DFT based<br />
calculations performed on intermetallic compounds <strong>of</strong> this type (with hydride forming metals being<br />
Ti, Zr, Hf <strong>and</strong> hydride non-forming metals Ni, Fe) <strong>and</strong> <strong>the</strong>ir hydrides are presented. The electronic<br />
structure <strong>and</strong> bonding in those materials as a function <strong>of</strong> composition <strong>and</strong> hydrogen content is<br />
discussed. In addition, <strong>the</strong> correlation between <strong>the</strong>oretical findings <strong>and</strong> experimental results is<br />
considered.<br />
