Vanadium–gallium tape is used in the highest field magnets (magnetic fields of 17.5 T). The structure of the superconducting A15 phase of V 3 Ga is similar to that of the more common Nb 3 Sn. [1] In conditions where the magnetic field is higher than 8 T and the temperature is higher than 4.2 K, Nb 3 Sn and V 3 Ga see use.
Gallium-70 can decay through both beta minus decay and electron capture. Gallium-67 is unique among the light isotopes in having only electron capture as a decay mode, as its decay energy is not sufficient to allow positron emission. [31] Gallium-67 and gallium-68 (half-life 67.7 min) are both used in nuclear medicine.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Superconducting wires/tapes/cables usually consist of two key features: The superconducting compound (usually in the form of filaments/coating) A conduction stabilizer, which carries the current in case of the loss of superconductivity (known as quenching ) in the superconductoring material.
Diamagnetic materials, like water, or water-based materials, have a relative magnetic permeability that is less than or equal to 1, and therefore a magnetic susceptibility less than or equal to 0, since susceptibility is defined as χ v = μ v − 1. This means that diamagnetic materials are repelled by magnetic fields.
Gallium and germanium are used in semiconductors, while germanium is also used in infrared technology, fibre optic cables and solar cells. Antimony is used in bullets and other weaponry, while ...
Remanence of audio tapes, referred to quarter-inch tape width, varies from around 1100 G for basic ferric tapes to 3500 G for Type IV tapes; [5] advertised remanence of the 1986 JVC Type IV cassette reached 4800 G. [6] Coercivity is a measure of the external magnetic flux required to magnetize the tape, and an indicator of the necessary bias level.
Data is stored in the magnetic media, such as hard drives, floppy disks, and magnetic tape, by making very small areas called magnetic domains change their magnetic alignment to be in the direction of an applied magnetic field. This phenomenon occurs in much the same way a compass needle points in the direction of the Earth's magnetic field.
