ferrimagneticn.adj.

Brit.

/ˌfɛrɪmaɡˈnɛtɪk/, U.S.

/ˌfɛrᵻˌmæɡˈnɛdɪk/

Origin: Formed within English, by compounding. Etymons: ferri- comb. form, magnetic adj.

Etymology: < ferri- comb. form + magnetic adj. In use as noun after French ferrimagnétique, noun (L. Néel 1950, in Ann. de l'Institut Fourier 1949 1 180). With the use as adjective, compare French ferrimagnétique , adjective (1950 or earlier). Compare earlier ferrimagnetism n., ferromagnetic n., ferromagnetic adj.

Physics.

A. n.

2012 R. J. Singh Solid State Physics xi. 441 Ferrimagnetics have resistivities in the range of 10²–10⁴ Ωcm, so they can be used as semiconductors.

B. adj.

Exhibiting ferrimagnetism; (also) of or relating to ferrimagnetism.
