为了阐明纵向磁场（LMF）对三氟乙酸基金属有机分解法超薄一次涂覆工艺（UTOC-MOD（Y，Gd）BCO-CCs）制备的Y0.77Gd0.23Ba2Cu3O7-δ涂覆导体（UTOC-MOD（Y，Gd）BCO-CCs）的影响，并了解BaHfO3纳米颗粒（BHO-NPs）对此的贡献，我们研究了大范围内的临界电流密度Jc温度和磁场条件。我们发现，在含有（w/）和不含（w/o）BHO-NPs的样品中，在整个条件下，LMF构型与面内横向磁场构型相比有所增加。在较高温度下，使用 BHO-NP 样品中的 LMF 配置带来的改进非常显着，这表明将 BHO-NP 引入 UTOC-MOD (Y,Gd)BCO-CC 对于 LMF 直流电缆应用将非常有用。
To clarify the effects of longitudinal magnetic field (LMF) on Y0.77Gd0.23Ba2Cu3O7-δcoated conductors fabricated by the trifluoroacetic-acid based metal organic decomposition method with the ultra-thin-once-coating process (UTOC-MOD (Y,Gd)BCO-CCs), and to understand the contributions of BaHfO3nanoparticles (BHO-NPs) to this, we investigated the critical current density Jcunder a wide range of temperature and magnetic field conditions. We found that Jcin the LMF configuration increased compared to those in the in-plane transverse magnetic field configuration under whole conditions in samples both with (w/) and without (w/o) BHO-NPs. Jcenhancement due to the LMF configuration was remarkable in the w/ BHO-NPs sample at higher temperatures, indicating that introduction of BHO-NPs to UTOC-MOD (Y,Gd)BCO-CC would be useful for LMF DC cable applications.
