Weak ferromagnetism in hexagonal Mn3Z (Z=Sn, Ge, Ga) alloys
Bendegúz Nyári, András Deák, László Szunyogh
We present combined spin model and first principles electronic structure calculations to study the weak ferromagnetism in bulk MnZ (Z=Sn, Ge, Ga) compounds. The spin model para…

Vapour sensing properties of graphene-covered gold nanoparticles
Gábor Piszter, Krisztián Kertész, György Molnár +3
We investigated the vapour sensing properties of different graphene-gold hybrid nanostructures. We observed the shifts in the optical spectra near the local surface plasmon resonan…

Exchange interactions from a nonorthogonal basis set: from bulk ferromagnets to the magnetism in low-dimensional graphene systems
László Oroszlány, Jaime Ferrer, András Deák +2
We present a computational method to determine the exchange constants in isotropic spin models. The method uses the Hamiltonian and overlap matrices computed from density functiona…
