Autor: Morari, C., Allmaier, H., Beiuşeanu, F., Jurcuţ, T., Chioncel, L.

Publikováno v: Phys. Rev. B 85 085413 (2012)

We present a study of the electronic and magnetic properties of the multiple-decker sandwich nanowires ($CP-M$) composed of cyclopentadienyl (CP) rings and 3d transition metal atoms (M=Ti to Ni) using first-principles techniques. We demonstrate using

Absence of halfmetallicity in defect-free Cr, Mn-delta-doped Digital Magnetic Heterostructures

Autor: Beiuşeanu, F., Horea, C., Macocian, E. -V., Jurcuţ, T., Vitos, L., Chioncel, L.

Publikováno v: Phys. Rev. B 83 125107 (2011)

We present results of a combined density functional and many-body calculations for the electronic and magnetic properties of the defect-free digital ferromagnetic heterostructures obtained by doping GaAs with Cr and Mn. While local density approximat

Electronic correlations in short period (CrAs)$_n$/(GaAs)$_n$ ferromagnetic heterostructures

Autor: Chioncel, L., Leonov, I., Allmaier, H., Beiuseanu, F., Arrigoni, E., Jurcut, T., Pötz, W.

Publikováno v: Phys. Rev. B 83 035307 (2011)

We investigate half-metallicity in [001] stacked (CrAs)$_n$/(GaAs)$_n$ heterostructures with $n \leq 3$ by means of a combined many-body and electronic structure calculation. Interface states in the presence of strong electronic correlations are disc
