"Type-I superconductivity in ScGa3 and LuGa3 single crystals." <i>Physical Review B,</i> 85, (2012) American Physical Society: 174514. http://dx.doi.org/10.1103/PhysRevB.85.174514.https://hdl.handle.net/1911/70622We present evidence of type-I superconductivity in single crystals of ScGa3 and LuGa3, from magnetization, specific heat, and resistivity measurements: low critical temperatures Tc = 2.1–2.2 K; field-induced secondto first-order phase transition in the specific heat, critical fields less than 240 Oe; and low Ginzburg-Landau coefficients κ ≈0.23 and 0.30 for ScGa3 and LuGa3, respectively, are all traits of a type-I superconducting ground state. These observations render ScGa3 and LuGa3 two of only several type-I superconducting compounds, with most other superconductors being type II (compounds and alloys) or type I (elemental metals and metaloids).engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
