1904 A. 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’.
1904 A. Schuster Introd. Theory Optics xii. 290 A simple and rational connexion between the Zeeman effect and magneto-gyric properties.
1911 Encycl. Brit. XVI. 616/2 A. Schuster distinguishes substances with regard to their action on polarized light as follows:..if the rotation be due to a magnetic field, magnetogyric.
2. Designating the ratio of the magnetic moment of an atom or particle to its angular momentum.

1965 M. G. Scroggie Electron in Electronics ix. 204 γs, the magnetogyric ratio for spin, is different from the orbital γ, being practically twice as large.
1972 Science 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.
1974 McGraw-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 ¼ that of protons.
1987 K. A. Rubinson Chem. Analysis xix. 765 γ is a constant, the value of which depends on the identity of the nucleus; it is called the magnetogyric ratio.
