Polaronic ferromagnetism in conducting polymers
Ferromagnetic behavior at room temperature is reported in metal-free-conducting polymer samples of poly(3-methylthiophene) doped with ClO 4 -. Magnetic moments associated with spin 1/2 positive polarons are possibly ...
Sonochemical synthesis and magnetism in co-doped ZnO nanoparticles
The understanding and control of ferromagnetism in diluted magnetic semiconducting oxides (DMO) is a special challenge in solid-state physics and materials science due to its impact in magneto-optical devices and spintronics. ...
Spin-resolved local density of states for an Anderson adatom in a ferromagnetic island
In this work, we investigate theoretically the spin-resolved local density of states (SR-LDOS) of a ferromagnetic (FM) island hybridized with an adatom, which is described by the Single Impurity Anderson Model (SIAM). Our ...
Ferromagnetism in layered metastable 1T-CrTe2
(IOP Publishing, 2015-05)
We have synthesized for the first time the metastable compound 1T-CrTe2. We have done its complete structural characterization and measured its magnetization, specific heat and electrical resistivity between 4 and 330 K. ...
Magnetic behavior of poly(3-methylthiophene): Metamagnetism and room-temperature weak ferromagnetism
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 ...
Ferromagnetic nanoclusters formed by Mn implantation in GaAs
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 ...
