Lande g-factor: In atomic physics, the Lande g-factor, named after Alfred Lande, is a multiplicative term that appears in the expression for the energy levels of an atom in a weak magnetic field. A g-factor (also called g value or dimensionless magnetic moment) is a dimensionless quantity that characterizes the magnetic moment and angular momentum of an atom, a particle or the nucleus. It is essentially a proportionality constant that relates the observed magnetic moment μ of a particle to i 2010-07-08 · Abstract: We present the first terrestrial measurement of the Lande g factor of the 5D5/2 state of singly ionized barium. Measurements were performed on single Doppler-cooled 138Ba+ ions in a linear Paul trap. 1999-01-01 · The anisotropy of the g factor is thus determined as a function of the well width. No difference is found between the components of the g factor parallel and perpendicular to the growth axis for a 12 nm wide QW, whereas a clear anisotropy is measured for narrower QW. 2008-11-01 · Fig. 1(b) displays the electron g ∥ factor, as a function of the square root of the transversal area α of the wire, for QWWs both cylindrical and with square transversal sections. Calculations were performed for B = 5 T. The g ∥ factor depends, in principle, on the shape of the transversal section of the wire, as one may note from Fig. 1(b).

Lande g factor

It allowed them to express the resultant splittings of the spectral lines in terms of the z-component of the total angular momentum, mj. - The value of the Lande’ g factor (nominal = 2.0036) for this system and its error. - The variation in the magnetic field over the area of the DPPH sample. As you have seen, the absorption appears as symmetrical dips in an otherwise constant signal.

Mark; Abstract The role of the Laude g-factor in atomic spectroscopy is explored through theoretical studies for Ne I and Ne II where some experimental values are available. (also g-factor), a factor in the formula for the splitting of energy levels in a magnetic field that determines the scale of splitting in relative units. It also determines the relative magnitude of the gyromagnetic ratio. The Landé splitting factor was introduced by the German physicist A. Landé in 1921. Lande´ g Factors and Orbital Momentum Quenching in Semiconductor Quantum Dots Craig E. Pryor and Michael E. Flatte´ Department of Physics and Astronomy and Optical Science and Technology Center, University of Iowa, Iowa City, Iowa 52242, USA Electron G - Factor. Electron is associated with three magnetic moments namely, spin angular , orbital angular and total angular momentum. Based on this, there are three g factors, electro spin g factor, orbital g-factor and Lande g factor.

The g-factor further governs the spin splitting in an external magnetic ﬁeld, being of crucial importance for numerous spintronics concepts.1 Low-temperature val- Eq.16 is used in calculating g-factor. As shown on this page, vector potential A includes exponential function, so we obtain the spin-magnetic field interaction from Eq.7 and Eq.16, as follows, (Eq.17) As you notice, we define spin angular momentum is "1/2", so electron g-factor (= g e) becomes "2". So g-factor "2" is not a natural thing. Abstract We have simultaneously measured the Lande g factor, the effective magnetization, M eff, and the uniaxial anisotropy, H k, and the Gilbert damping parameter α, as a function of Permalloy film thickness from 2.5 to 50 nm. The Landé-g factor obtained using these formulas compares within the 5% with the reported results of Brosig et al.

In der Physik gibt der Landé Faktor (nach Alfred Landé) oder gyromagnetische Faktor für ein geladenes Teilchen im Magnetfeld an, um wie viel stärker sich der Spin auf seine Energie auswirkt als ein gleich großer Bahndrehimpuls. this paper concerning the conventional sign of the g factor for electron spin will be seen by Introduction. The g factor, ®rst introduced by Lande¬ [1] to explain. Oct 26, 2004 We show that the electron and hole Lande g factors in self-assembled III-V quantum dots have a rich structure intermediate between that The energy levels strongly depend on the combined effects of external magnetic field and spin-orbit interaction strength. •.
