摘要：

We have established that by using different temperature gradients and temperature regimes it is possible to obtain two types of Bi2201 single crystals from the same solution-melt KCI: on the solution-melt surface and in gas cavities formed in the melt volume. These two types crystals differ in both structural perfection and superconducting properties. Only Bi2201 single crystals formed by a "free" growth in cavities display reproducible structural perfection and superconducting properties and can be recommended to use in precision experiments to study the mechanism of HTS.
