The Zener model of ferromagnetism predicts that higher values of Curie temperature (CT) can be achieved by materials containing greater doping concentrations and hole concentrations. However, the prediction value is significantly higher than those from experiments with high doping concentrations. This discrepancy is resolved by an improved theoretical prediction for CT of 3d transition-metal-doped GaAs . Cr -doping results in higher CT than the Mn -doped GaAs. Maximum CT of Ga 1-x Mn x As is 215 K with 13.9% doping concentration. Room temperature CT can be achieved by 11.3% Cr -doped GaAs . Maximum CT of Ga 1-x Cr x As can reach 514.4 K with 31.7% doping concentration.

<p>An examination of the first-row transition metal doped boron clusters, B<sub>14</sub>M (M = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) in the neutral state, is carried out using DFT quantum chemical calculations. The lowest-energy equilibrium structures of the clusters considered are identified at TPSSh/ 6-311+G(d) level. It is found that the structural patterns of doped species evolve from exohedrally capped quasi-planar structure B<sub>14</sub> to endohedrally doped double ring tubular when M goes from Sc to Cu. The B<sub>14</sub>Ti and B<sub>14</sub>Fe turn out to be remarkable species due to their enhanced thermodynamic stabilities with larger average binding energies. Their electronic properties can be understood in terms of the density of state (DOS).</p><p> </p>

In this paper, we report the multiferroic and piezoelectric behavior observed in transition-metal doped ZnO films. The experimental results indicated that the Co-doped ZnO films deposited by magnetron sputtering possess a Curie temperature higher than 700K, and the magnetic moments of Co are intimatedly correlated to the doping concentration and the substrate. A giant magnetic moment of 6.1 B/Co is observed in (4 at.%) Co-doped ZnO films. Ferroelectric and ferromagnetic behaviors simultaneously were also obtained in V and Cr doped ZnO films on Pt(111)/Ti/SiO2/Si(100) substrates by reactive sputtering method, revealing a multiferroic nature. The high piezoelectric d33 coefficient 80-120 pm/V has also been achieved by Cr and V substitutions, which could make Cr-doped or V-doped ZnO a promising material in piezoelectric devices.
