Determination of the Upper Critical Field of a Single Crystal LiFeAs: The Magnetic Torque Study up to 35 Tesla
N. Kurita, K. Kitagawa, K. Matsubayashi +6
We report on the upper critical field B_c2 of a superconducting LiFeAs single crystal with T_c~16 K, determined from magnetic torque measurements in dc-magnetic fields up to 35 T a…
Quasi-Two-Dimensional Fermi Surfaces and Coherent Interlayer Transport in KFeAs
M. Kimata, T. Terashima, N. Kurita +15
We report the results of the angular-dependent magnetoresistance oscillations (AMROs), which can determine the shape of bulk Fermi surfaces in quasi-two-dimensional (Q2D) systems,…
Upper Critical Field of Pressure-Induced Superconductor EuFeAs
Nobuyuki Kurita, Motoi Kimata, Kota Kodama +7
We have carried out high-field resistivity measurements up to 27\,T in EuFeAs at \,=\,2.5\,GPa, a virtually optimal pressure for the -induced superconductivity, where…
Magnetotransport studies of EuFeAs: the influence of the Eu magnetic moments
Taichi Terashima, Nobuyuki Kurita, Akiko Kikkawa +4
We report resistivity and Hall effect measurements on EuFeAs at ambient pressure and 28 kbar and magnetization measurements at ambient pressure. We analyze the temperat…
Two- and Three-Dimensional Fermi Surfaces and their Nesting Properties in Superconducting BaFe2(As1-xPx)2
T. Yoshida, I. Nishi, S. Ideta +9
We have studied the three-dimensional shapes of the Fermi surfaces (FSs) of BaFe2(As1-xPx)2 (x=0.38), where superconductivity is induced by isovalent P substitution, by angle-resol…
High-Pressure Electrical Resistivity Measurements of EuFe2As2 Single Crystals
N. Kurita, M. Kimata, K. Kodama +7
High-pressure electrical resistivity measurements up to 3.0GPa have been performed on EuFe2As2 single crystals with residual resistivity ratios RRR=7 and 15. At ambient pressure, a…
