Abstract. The Magnetospheric Multiscale mission (MMS1) data for 8 months in the winter periods of 2017–2018 and 2018–2019, when MMS had its apogee upstream solar wind Earth's bow shock, are used to study linear magnetic holes (LMHs). These LMHs characterized by a depression more than 50 % rotation background field less then 10?. A total 406 found and, based on their magnetoplasma characteristic...

The formation of nonlinear ion-acoustic waves is studied in a degenerate magnetoplasma accounting for quantized and trapped electrons. Relying on the reductive perturbation technique, three-dimensional Zakharov–Kuznetsov (ZK) equation derived, admitting solitary wave solution with modified amplitude width parameters. stability ZK also discussed using k-expansion method. Subsequently, numerical ...

Structures consisting of an InGaAs/GaAs quantum well and a ferromagnetic 〈Mn〉 δ layer separated by narrow 3–10 nm spacer have been studied using the optically detected cyclotron resonance (ODCR). Despite strong disorder in these structures, photoluminescence charge carriers indicates ODCR upon absorption far infrared regions with maximum magnetic fields much lower than those expected for typica...
