MAGNETIC SWITCHING EFFECT IN SPIN FIELD-EFFECT TRANSISTORS
International Journal of Modern Physics B, 2010Taking account the presence of external magnetic field, we study the conductance properties in spin field-effect transistors (SFET). It is shown that the conductance of the SFET exhibits an excellent magnetic switching characteristic for high potential barriers, and it is more and more pronounced with the potential barrier strength increasing ...

Longitudinal Magnetic Field Effect
2007Chapter 4 covers various phenomena observed when the transport current is applied to a long superconducting cylinder or tape in a longitudinal magnetic field. It is empirically known that the force-free model, which assumes a current flow parallel to the flux lines, explains some of such phenomena.

Electronic carriers tend to circle flux lines when they move in magnetic fields. Under the circumstances discussed in Sec. 2.8 and shown in Fig. 2.4, these circular paths are extended into helices with radii, pitch distances, and frequencies of circulation. The radius referred to here is the magnetron radius described in Sec.

Magnetic field effect on hemin
Physica B: Condensed Matter, 2001Abstract Magnetic behaviour of hemin has been investigated by means of magnetostatic methods, AC-susceptibility measurements and EPR spectroscopy. The measurements were made using polycrystalline and oriented samples of hemin in the temperature range 2.3–292 K and in magnetic fields up to 6 T.

Magnetoacoustic Effects in Tilted Magnetic Fields
Physical Review, 1962Abstract : It is shown that the entire Fermi surface can be mapped by using geometric resonances in the sound attenuation in tilted magnetic fields and the drift velocity of the carriers along the magnetic field simultaneously determined. The general features of the phenomena considered do not prove dependent on the particular models used in our ...

Theory of Hyperfine Field-Induced Organic Magnetic Field Effects
2018In this chapter, we discuss the essence of hyperfine-field induced magnetic field effects in organic semiconductors originating from spindependent reactions between electron and hole polarons. The basic picture we employ is that of two spin-1/2 polarons, each localized on a site in the semiconductor, where one of the polarons incoherently hops to the ...

Magnetic field effect upon albumin immobilization
2006Copolymers of methyl methacrylate (MMA) with 2, 3 epoxypropyl methacrylate (GMA) were tested as matrices for the coupling of the bioactive products. The preparation of polymeric matrices was realized by classic emulsion polymerization (CW) and also comparatively obtained through unconventional procedure in the presence of a magnetic field (MF) of 1500 ...

Magnetic field effects in proteins
Molecular Physics, 2016ABSTRACTMany animals can sense the geomagnetic field, which appears to aid in behaviours such as migration. The influence of man-made magnetic fields on biology, however, is potentially more sinister, with adverse health effects being claimed from exposure to fields from mobile phones or high voltage power lines.
