In HTS films the Yttrium can be replaced by Rare Earth metals like Dysprosium, Erbium or Neodymium, for example. The resulting compounds also show Tc around 90K and the modification can be beneficial for certain applications.
For example, NdBCO films exhibit very high thermal stability and are commonly used as seed for growth of bulk YBCO disks. Many research insitutes and companies rely on our NdBCO seeds.
We supply the seed crystals cut in customer-defined size cut by certified partners with high yield.
