以9.0 at镍合金为原料，采用冷轧退火（RABiTS）法制备了立方体织构带。为了得到Y Ba2Cu3O7−δ (YBCO)型超导体的柔性非磁性衬底。在Ni-9.0 at中测量到高达96%的立方体取向。% W合金带。第一次脉冲激光镀膜实验表明，在衬底上形成了缓冲层和YBCO层的外延生长。自场温度为77 K，临界电流密度Jc可达1.10 MA cm−2。
Cube textured tapes were prepared by cold rolling and annealing (RABiTS method) from nickel alloyed with 9.0 at.% tungsten in order to get a flexible nonmagnetic substrate for superconductors of the Y Ba2Cu3O7 − δ (YBCO) type. A fraction of up to 96% of cube orientation was measured for the Ni–9.0 at.% W alloy tape. First coating experiments by pulsed laser deposition revealed an epitaxial growth of the buffer and the YBCO layers on the developed substrate. Critical current densities Jc of up to 1.10 MA cm − 2 were measured at 77 K in self-field.
