magnetostrictionn.

Brit.

/maɡˌniːtə(ʊ)ˈstrɪkʃn/, U.S.

/mæɡˈˌnɛdoʊˈstrɪkʃən/,

/mæɡˈˌnidoʊˈstrɪkʃən/

Origin: A borrowing from Latin, combined with an English element. Etymons: magneto- comb. form, Latin strictiōn-, strictiō.

Etymology: < magneto- comb. form + classical Latin strictiōn-, strictiō (see striction n.). Compare French magnétostriction (1900).

Dependence of the state of strain of a body (and hence its dimensions) on its state of magnetization. Frequently attributive.

1896 London, Edinb. & Dublin Philos. Mag. 5th Ser. 41 454 (heading) On the effects of magnetic stress in magnetostriction.

1926 Jrnl. Iron & Steel Inst. 113 657 A reciprocal relation between magneto-striction and the effect of stress on magnetisation was investigated experimentally.

1937 Nature 18 Dec. 1068/2 A magnetostriction oscillator has been developed which produces intense audible vibrations of frequencies of 8000 cycles per second, capable of fracturing glass.

1959 H. Barnes Oceanogr. & Marine Biol. 74 The magneto-striction effect depends upon the fact that when certain metals, notably nickel, are placed in a varying magnetic field they undergo mechanical changes... As with the mechanical changes brought about by the piezo-electric effect, these also may be transmitted to a medium and, if they are sufficiently rapid, ultrasonic waves are produced.

1966 C. R. Tottle Sci. Engin. Materials vi. 138 Iron crystals expand along the direction of magnetization and contract at right-angles to it, whereas nickel contracts along the magnetization direction and expands perpendicular to it. This phenomenon is known as magnetostriction.

1989 Guardian 4 July 38/2 One other such curious phenomenon is known as magnetostriction..in which solid materials change their dimensions when subjected to a magnetic field.
