Polaronic ferromagnetism in conducting polymers
(2001-12-01)
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
(2013-07-01)
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
(2013-06-01)
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 ...
Room temperature ferromagnetic behavior in pressed pellets of doped poly (3-methylthiophene)
(Taylor & Francis Ltd, 2002-01-01)
Room temperature ferromagnetic behavior has been observed in pressed pellets of doped poly(3-methylthiophene). In this work we show that thermoremance data taken in two different ways favours the interpretation of data in ...
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) ...
Quantum spin tunneling of magnetization in small ferromagnetic particles
(ELSEVIER SCIENCE BV, 2009)
An approach is presented that can also account for the description of small ferromagnetic particle magnetization tunneling. An estimate of the saturation value of an external applied magnetic field along the easy axis is ...
Quantum spin tunneling of magnetization in small ferromagnetic particles
(Elsevier B.V., 2009-04-01)
An approach is presented that can also account for the description of small ferromagnetic particle magnetization tunneling. An estimate of the saturation value of an external applied magnetic field along the easy axis is ...
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. ...
The ferromagnetic behaviour of conducting polymers revisited
(Iop Publishing Ltd, 2008-01-23)
The magnetic properties of doped pellets of poly(3-methylthiophene) showing room temperature ferromagnetic behaviour have been discussed in a previous article. The magnetic behaviour was attributed to a weak ferromagnetic ...
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 ...
