We have investigated the hyperfine fields at Be site in a single crystal UBe13 with Tc ≈0.87 K by means of the 9Be nuclear magnetic resonance (NMR). For an applied field parallel to [001] direction, a well split 9Be NMR spectrum was obtained. From the Clogston–Jaccarion plot, we determined an isotropic hyperfine field for Be(I) site and anisotropic hyperfine fields for Be(II) site.
