Magnetostriction of TbxHo0.75−xPr0.25(Fe0.9B0.1)2 (x=0–0.3) compounds

Magnetomechanical properties of epoxy-bonded (Tb0.3Dy0.7)1−xPrxFe1.55(0 ⩽x⩽ 0.4) pseudo-1–3 magnetostrictive composites

“…While Terfenol-D and its composites are useful, the heavy rare earths Tb and Dy that constitute the Terfenol-D composition are both expensive and rare in the Earth. Due to the much lower cost and greater abundance of the light rare earth Pr than the heavy rare earths Tb and Dy, the development of Laves alloys with a high Pr content has been a hot research topic in recent years [15][16][17][18][19][20][21][22][23]. In order to effectively synthesize high Pr-containing Laves phases, it is generally required to introduce an additional element B or Co into the synthesis process to stabilize the crystal lattice of the Laves phases [15][16][17][18][19][20][21][22].…”

For the synthesis of stabilizer (B or Co)free, light rare earth (Pr)-containing Laves alloys, few reports have been made to date even though it is known from the (Tb 0.3 Dy 0.7 ) 0.7 Pr 0.3 Fe y system that the alloy will be nearly single cubic Laves phase with an MgCu 2 -type structure if an optimal Fe content y of 1.55 is adopted in the (Tb 0.3 Dy 0.7 ) 0.7 Pr 0.3 Fe y system [23].…”
