ＮｄＡｌＯ３晶体是一种新型的高温超导薄膜和ＬＣＭＯ巨磁阻膜基片材料，具有低的介电常数和介电损耗，与ＹＢＣＯ有良好的晶格匹配。与ＬａＡｌＯ３晶体（～５００℃）相比，ＮｄＡｌＯ３晶体具有相变温度高（＞１５００℃）的优点，这样，有利于ＹＢＣＯ薄膜的外延生长。我们采用感应加热提拉法生长ＮｄＡｌＯ３晶体。铱坩锅尺寸６０×５５ｍｍ，拉速１～３ｍｍ／ｈ，转速１０～３０ｒ／ｍｉｎ，气氛Ｎ２，第一次生长采用ＬａＡｌＯ３晶体作为籽晶，＜００１＞方向生长，生长出尺寸达２５×６０ｍｍ的无云层、无气泡、无开裂、质量优良的ＮｄＡｌＯ３晶体。
NdAlO3 crystal is a new type of high temperature superconducting thin film and LCMO giant magnetoresistive film substrate material with low dielectric constant and dielectric loss, and YBCO has a good lattice match. Compared with LaAlO3 crystal (~ 500 ℃), NdAlO3 crystal has the advantage of high phase transition temperature (> 1500 ℃), which is in favor of the epitaxial growth of YBCO film. We grow NdAlO3 crystals by induction heating. Iridium crucible size 60 × 55mm, pulling speed of 1 ~ 3mm / h, speed 10 ~ 30r / min, the atmosphere N2, the first growth using LaAlO3 crystal as a seed, <001> growth, grow up to size 25 × 60mm cloudless, no bubbles, no cracking, high quality NdAlO3 crystal.
