| Article Name : | | | MAGNETIC AND MAGNETOSTRICTIVE PROPERTIES OF TERFENOL-D LIKE ALLOYS | | Author Name : | | | Jitendra Pendharkar , Manohar Nyayate. | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-6162 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | It was observed that RFe2 compounds exhibits large Magnetostriction effects (1,2) at room temperature, and Terfenol-D which is a composition of Tb0.3Dy0.7Fe1.97 exhibits maximum Magnetostriction of 1450 micro strain at room temperature in polycrystalline form. The change in the magnetic and magnetostrictive properties has been studied by changing its composition. The Iron is replaced by Cobalt which is another d block ferromagnetic element in first case and in second sample Dysprosium is replaced by Gadolinium which is another rare earth element in lanthanide series. The change again gives good Magnetization at 3oK as well as low coercivity. But due to cobalt the combinations turns to be paramagnetic at room temperature. Adding Gadolinium instead of Dysprosium causes net change of 600 micro strain but showed negative strain of 150 micro strains. | | Keywords : | | |
