摘要

Preparation of superconducting epitaxial film using the method of liquid phase epitaxial growth comprising the steps of:P P (1) melting the oxides of bismuth, calcium, strontium, and copper or the oxides of thallium, calcium, barium, and copper at temperature in the range of 900° C. to 950° C. to form a meP P (2) contacting the melt in (1) with magnesium oxide or mono crystalline materials;PP(3) lowering the temperature of the melt at a rate of 0.3°-2° C./min until the temperature is within the range of 820° C. to 890° C.;PP (4) separating the melt and the magnesium oxide substrate or mono crystalline material to obtain a superconducting epitaxial film; and PP(5) quenching said film in (4) until the temperature thereof is at room temperature, whereby a superconducting epitaxial film having a thickness of 40 to 150 &mgr;m is obtained.

(2)使(1)中的熔体与氧化镁或单晶材料接触;

(3)以0.3°-2°C / min的速率降低熔体的温度,直到温度在820°C至890°C的范围内;

(4)分离熔体和氧化镁衬底或单晶材料,以获得超导外延膜; & P& P&(5)在(4)中淬火所述膜直至其温度达到室温,从而获得厚度为40-150μm的超导外延膜。
