Temperature dependent resistivity and susceptibility show a superconducting transition temperature, Tc, just below 31 K both with sharp transitions. The upper critical field parallel to the ab-plane, Hc2 ab, is above 77 Tesla while that along the c-axis direction, Hc2 c, is just above 36 Tesla, yielding a low superconducting anisotropy ratio ~ 2. The estimated inter-plane coherence length based on the Ginzburg-Landau (G-L) theory indicates BaFe2(As0.68P0.32)2 is still above the point for a dimensional crossover inferring the superconducting layers are not weakly-coupled in this system. The critical current density at 5 K obtained from magnetization loops measurement show a modest Jc as high as 105 A/cm2.}, pages = {1178--1181}, title = {Upper critical fields and critical current density of BaFe2(As0.68P0.32)2 single crystal}, volume = {150}, year = {2010}, yomi = {カドワキ カズオ} }
