Meaning of Einstein–de Haas effect | Babel Free

Definitions

A physical phenomenon in which a change in the magnetic moment of a free body causes the body to rotate, as a consequence of the conservation of angular momentum.

Equivalents

Examples

“This relation between the magnetic moment and the angular momentum is demonstrated by the Einstein–de Haas effect, discovered in 1915, in which a ferromagnetic rod is suspended vertically, along its axis, by a thin fibre (see⟳ Fig 1.2).”

“Because of this transfer⟳, an initially spin-polarized dipolar condensate can dynamically generate⟳ vortices in a process⟳ resembling the Einstein–de Haas effect.”

“In this chapter, we explore⟳ the possibility of using the spin⟳ degree of freedom of electrons, which has been disregarded for "conventional" molecular motors, and of resorting to the principle of the Einstein–de Haas effect, a century-old but still intriguing magnetic phenomenon.”
