magnetogyric, a. Physics.|mægˌniːtəʊˈdʒaɪərɪk|
[f. magneto- + Gr. γῦρ-ος ring, circle + -ic.]
1. Pertaining to or exhibiting the Faraday effect (Faraday 1).
1904A. Schuster Introd. Theory Optics xii. 272 All substances turn the plane of polarization when they are traversed by light in the direction of a magnetic field. They become therefore ‘magneto-gyric’. Ibid. 290 A simple and rational connexion between the Zeeman effect and magneto-gyric properties.
2. Applied to the ratio of the magnetic moment of an atom or particle to its angular momentum.
1965M. G. Scroggie Electron in Electronics ix. 204, γs, the magnetogyric ratio for spin, is different from the orbital γ, being practically twice as large. 1967Condon & Odishaw Handbk. Physics (ed. 2) viii. ix. 113/1 The term gN(e/2Mc) is often replaced by γ, the magnetogyric ratio; hence, µ= γħI. 1972Science 27 Oct. 364/1 As long as H1 is applied, M precesses..at a frequency given by the Larmor relation ωR= γH1 (in radians per second) where γ is the magnetogyric ratio of the nucleus. 1974McGraw-Hill Yearbk. Sci. & Technol. 314/2 Compared to H1, the C13 nuclei are much weaker magnets. The magnet strength (magnetogyric ratio γ) is only about 1/4 that of protons. |
