K. Terryll et al., NANOCRYSTALLINE YBA2CU4O8 C-ORIENTED FILMS PREPARED BY ND-YAG LASER DEPOSITION, Physica. C, Superconductivity, 235, 1994, pp. 683-684
Single phase YBa2Cu4O8 films were obtained by Nd:YAG pulsed laser depo
sition and subsequent annealing. STM / SEM characterization reveal tha
t these films consist of strongly c-oriented nano-sized grains. The ob
served rather low critical current [J(c)(5 K, H = 0) approximate to 1.
10(3) A/cm(2)] make these films promising for fast response low field
sensor applications.
