Dy2fe14b

The thermodynamic and magnetic properties for Dy 2 Fe 14 B, a principal constituent of rare-earth magnets, were investigated as a function of temperature via calorimetric measurements. Its standard entropy, Δ 0 T S m ∘, was obtained from the molar heat capacity, C p, m ∘, at 2 − 850 K using Debye-Einstein spin-wave functions.The standard enthalpy of formation, Δ f H m ∘, was ... Web由于Dy2Fe14B、Tb 2Fe14B相的磁晶各向异性场远比Nd2Fe14B相的要强，居里温度也相对比较高，因此可以大大提高材料的矫顽力以及温度稳定性，对于矫顽力和使用温度要求较高的烧结钕铁硼材料中，通常会加入镝、铽等元素。

WebWe investigated the microstructural and magnetic property changes of DyF3/DyHx dip-coated Nd–Fe–B sintered magnets, as a function of the DyF3/DyHx mixing ratio. As the fraction of DyHx in a DyF3/DyHx mixed solution was increased (0 → 50 → 100%), there was a coincident gradual increase in coercivity (14.9 → 15.4 → 16.5 kOe).
