Reduction of the low-temperature bulk gap in samarium hexaboride under high magnetic fields
S. Wolgast, Y. S. Eo, K. Sun +5
SmB exhibits a small (15-20 meV) bandgap at low temperatures due to hybridized and electrons, a tiny (3 meV) transport activation energy above 4 K, and surfac…
Experimental realization of field-induced XY and Ising ground states in a quasi-2D S=1/2 Heisenberg antiferromagnet
Yoshimitsu Kohama. Marcelo Jaime, Oscar E. Ayala-Valenzuela, Ross D. McDonald +3
High field specific heat, Cp, and magnetic susceptibility, \c{hi}, measurements were performed on the quasi-two dimensional Heisenberg antiferromagnet [Cu(pyz)2(pyO)2](PF6)2. While…
High Field behavior of the Spin Gap compound SrCu(BO)
Suchitra E. Sebastian, D. Yin, P. Tanedo +8
We report magnetization and heat capacity measurements of single crystal samples of the spin gap compound SrCu(BO). Low-field data show that the material has a singlet…
High Field Studies of the Hidden Order Transition in URuSi
M. Jaime, K. H. Kim, G. Jorge +2
We studied in detail the low temperature/high magnetic field phases of URuSi single crystals with specific heat, magnetocaloric effect, and magnetoresistance in magneti…
Effects of unreacted Mg impurities on the transport properties of MgB2
C. U. Jung, Heon-Jung Kim, Min-Seok Park +9
We synthesized polycrystalline MgB2 from a stoichiometric mixture of Mg and the 11 B isotope under different conditions. All the samples showed bulk superconductivity with Tc = 38~…
Anisotropic Superconductivity in Epitaxial MgB2 Films
M. H. Jung, M. Jaime, A. H. Lacerda +5
High-quality epitaxial MgB2 thin films prepared by pulsed laser deposition with Tc = 39 K offer the opportunity to study the anisotropy and robustness of the superconducting state…
Low-temperature electrical transport and double exchange in La(Pb,Ca)MnO
M. Jaime, P. Lin, M. B Salamon +1
The resistivity in the ferromagnetic state of flux-grown La_{2/3}(Pb,Ca)_{1/3}MnO_3 single crystals, measured in magnetic fields up to 7 T, reveals a strong quadratic temperature d…
