Field-induced quantum critical point in CeCoIn_5
Johnpierre Paglione, M. A. Tanatar, D. G. Hawthorn +7
The resistivity of CeCoIn_5 was measured down to 20 mK in magnetic fields of up to 16 T. With increasing field, we observe a suppression of the non-Fermi liquid behavior, rho~T, an…
Effects of Boron Purity, Mg Stoichiometry and Carbon Substitution on Properties of Polycrystalline MgB
R. A. Ribeiro, S. L. Bud'ko, C. Petrovic +1
By synthesizing MgB using boron of different nominal purity we found values of the residual resistivity ratio () from 4 to 20, which covers almost a…
Field-Induced Quantum Critical Point in CeCoIn5
Johnpierre Paglione, M. A. Tanatar, D. G. Hawthorn +7
The resistivity of the heavy-fermion superconductor CeCoIn5 was measured as a function of temperature, down to 25 mK and in magnetic fields of up to 16 T applied perpendicular to t…
Carbon doping of superconducting magnesium diboride
R. A. Ribeiro, S. L. Bud'ko, C. Petrovic +1
We present details of synthesis optimization and physical properties of nearly single phase carbon doped MgB2 with a nominal stoichiometry of Mg(B{0.8}C{0.2})2 synthesized from mag…
