Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We set up a theory of magnetomagnon resonances in diluted magnetic semiconductor quantum wires in the case of electron-magnon scattering. The magnetoconductivity xx is calculated using the usual Kubo formula. We found that for a nondegenerate statistics of quasi-one-dimensional electron gas xx shows oscillatory behavior characteristic of structures presenting manifestations of the size quantization effect in the presence of a quantizing magnetic field. Moreover, magnetomagnon resonances are predicted in the xx behavior as function of the electron cyclotron frequency. Another contribution to the conductivity pc, which is caused by the current carried by electron motion affected by the confinement potential, is calculated. As the confinement potential increases, for a fixed magnetic field value, pc decreases steeply similar to the case of GaAs quantum wires. For typical parameters of a Ga1-x Mnx As quantum wire we find xx = 10-9 S for a magnetic field of 10 T and temperature T=20 K. This magnon effect is two orders of magnitude greater than the magnetoconductivity due to phonons as reported in the literature thereby implying that in diluted magnetic semiconductor Ga1-x Mnx As quantum wires the exchange interaction is the main electron interaction channel. © 2007 American Institute of Physics.
