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 ...
Potts model on the Sierpinski gasket: A transfer-matrix approach
(Physical Review B, 1993)
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 ...
