diamagnetic
/ˌdʌɪəmaɡˈnɛtɪk
/adjective Physics
(Of a substance or body) tending to become magnetized in a direction at 180° to the applied magnetic field.Any remaining magnetic effects in diamagnetic materials are produced by the orbiting electrons....
- For example, placing diamagnetic metals such as aluminium or zinc at the centre of the phthalocyanines improves the photosensitization of the compound for use in PDT.
- In the iron diamagnetic form, magnetic anisotropy arises from the heme, aromatic moieties, and elements of secondary structure.
Derivatives
diamagnet
- A superconductor is a perfect diamagnet, but there is more than this involved in the Meissner effect.
- This force moves the small magnet up until the force from the bottom and top diamagnets equals one another.
- Superconductors are the strongest diamagnets, and many ordinary materials are weakly diamagnetic.
diamagnetically
- The upper graph shows the diamagnetically measured plasma stored energy W p and the line averaged electron density N e.
- One illustrated the diamagnetic properties of water and the other demonstrated diamagnetically stabilized magnetic levitation.
- An apparatus for demonstrating, investigating and observing Brownian motion and temperature of a medium, such as gas or liquid, uses a small particle which is diamagnetically suspended in the medium.
diamagnetism
/ noun ...- But his fame is certainly much greater than these concrete results alone might suggest - even if one were to include other formulae, such as the Landau diamagnetism of free electrons.
- While his brief mentions of diamagnetism and superconductors may enhance an understanding of Primer, his film deserves the sort of rigorous analysis that was brought to bear on The Matrix trilogy in last year's 10-disc set.
- Although diamagnetic effects are usually very small, one class of materials shows strikingly large diamagnetism: superconductors.
Origin
1846: coined by Faraday, from Greek dia 'through, across' + magnetic.
