Anisotropy of superconductivity of as-grown MgB${}_2$ thin films by molecular beam epitaxy

Y. Harada, M. Udsuka, Y. Nakanishi +1

Superconducting thin films of magnesium diboride (MgB${}_2$) were prepared on MgO (001) substrate by a molecular beam epitaxy (MBE) method with the co-evaporation conditions of low d…
