A cross-sectional diagram of a typical Terfenol-D actuator reveals the Terfenol-D rod, permanent magnets, and coil driver. Magnets bias the Terfenol-D magnetic domains for ac use. Versions biased for ...

THE temperature variation of the longitudinal magnetostriction of ‘Alcomax’ and some related alloys is being investigated, and the results so far obtained are shown in the accompanying graph. The ...

IN his experiments on the change of length by magnetisation, Joule (“Papers,” vol. i. p. 50) mentions that “the expansion, though very minute, is indeed so very rapid that it may be felt by the touch.

The stress-induced reorientation of the low-symmetry defects due to substitution atom pairs can give rise to an internal friction peak, Zener relaxation. It is one of the most representative point ...

The findings have been published in (Advanced Functional Materials, "Anisotropic Band-Split Magnetism in Magnetostrictive CoFe₂O₄"). Spin-wave spectrum of CoFe₂O₄ measured on the MAPS spectrometer ...

A new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting, has been discovered. A new class of magnets ...
