Ferromagnetic nanoclusters formed by Mn implantation in GaAs
(2005-02-14)
Ferromagnetic clusters were incorporated into GaAs samples by Mn implantation and subsequent annealing. The composition and structural properties of the Mn-based nanoclusters formed at the surface and buried into the GaAs ...

Defect induced room temperature ferromagnetism in high quality Co-doped ZnO bulk samples
(2021-04-05)
The nature of the often reported room temperature ferromagnetism in transition metal doped oxides is still a matter of huge debate. Herein we report on room temperature ferromagnetism in high quality Co-doped ZnO (Zn1−xCoxO) ...
Influence of nearest-neighbor Coulomb interactions on the phase diagram of the ferromagnetic Kondo model
(1999-12-01)
The influence of a nearest-neighbor Coulomb repulsion of strength V on the properties of the ferromagnetic Kondo model is analyzed using computational techniques. The Hamiltonian studied here is defined on a chain using ...
Magnetic behavior of poly(3-methylthiophene): Metamagnetism and room-temperature weak ferromagnetism
(2003-04-01)
A weak ferromagnetic phase is shown in pressed pellets of partially doped poly(3-methylthiophene) (P3MT) in the whole range from 1.8 to 300 K in magnetic measurements. Thermoremanence data have been used to estimate the ...
