摘要：Bulk MgB2was prepared by solid-state chemical sintering reaction using NaBH4and MgH2as starting materials under N2flow. The superconductive phase transition was observed at 39 K and the superconductive properties were comparable to those of a commercial product. Fine line patterns of MgB2with Tc= 36 K were fabricated on the surface of the pressed discs of mixed raw materials by ytterbium fiber laser irradiation. © 2008 The Japan Society of Applied Physics.
