A net magnetic moment of 1μB and 2μB are, respectively, found in the B- and C-doped structures mainly due to the partially filled dopant atom 2 p orbitals. Due to ferromagnetic coupling, magnetic moments from the neighbouring Zn atoms and the subsequent O atoms also contribute to the ...

In the present work, nickel doping, introduces empty or partially filled minority states at the Fermi level keeping the majority states occupied due to double exchange (RKKY) interactions. This suggests that nickel doping leads to 100% spin polarization and results in half metallicity in ZnS. The...
This procedure was performed in a glove box filled with Ar gas, where the oxygen and humidity content were less than 0.5 ppm. The mixture was sealed inside a tantalum tube. This procedure was operated in a home-made arc furnace. The sealed tantalum tube was then sealed into an ...
The energy bands of bulk LCO and HBCO are also plotted in Fig. 1 for comparison. For SLs, electronic properties around εF are still mainly controlled by Ag-eg bands, which are above the filled O/F-2p and Ag-t2g bands and below the empty Ti-3d/Zn-4s bands. We plot (dark cyan)...
Due to the fact that double exchange is a kind of mechanism happening between two magnetically active ions, i.e., partially-filled d-shells with different charge statuses, double exchange is irrelevant here in compounds with Zn fully-filled d-orbitals. Consequently, it is not possible for the...
The solid line is a guide for eyes; (b) carrier concentration dependence of the power factor for the typical light-band PbTe, and the heavy-band system: n-type ZrNiSn, n-type filled CoSb3 and p-type FeNbSb near 800 K. Reproduced from [59]. 3. Electronic Transport Properties of HH...
Actually, filled skuterudites and HH compounds, usually containing transition metal elements with localized d states, are heavy-band materials due to the flat valence band maximum or conduction band minimum [38,56]. Typically, the m* of these heavy-band materials are in the range of 2 me–...
