以[112]取向的枝晶血小板形式生长的TbxDyyHo1−x−yFe1.95的Laves相棒的磁化强度和磁致伸缩率随磁场H（−2200<H<2200 Oe）、压应力（20、30和40 MPa）和温度T（−60<T<80℃）的变化而变化。与Terfenol-D （Tb0.3Dy0.7Fe1.95）相比，含Ho合金具有较低的磁致伸缩和较低的磁滞回。样品组成选择沿最小近室温各向异性线（Tb0.3Dy0.7Fe1.95-Tb0.20Dy0.22Ho0.58Fe1.95）和Ho0.15和Ho0.30。
The magnetization and magnetostriction of a variety of Laves phase rods of TbxDyyHo1−x−yFe1.95 grown in the form of [112] oriented dendritic platelets were measured as a function of magnetic field H(−2200<H<2200 Oe), compressive stress (20, 30, and 40 MPa), and temperature T(−60<T<80 °C). Compared to Terfenol-D (Tb0.3Dy0.7Fe1.95), Ho containing alloys can have lower hysteresis with only slightly lower magnetostriction. Sample compositions were chosen both along a line of minimum near room-temperature anisotropy (Tb0.3Dy0.7Fe1.95–Tb0.20Dy0.22Ho0.58Fe1.95) and at Ho0.15 and Ho0.30 across the line.
