Crossover from commensurate to incommensurate antiferromagnetism in stoichiometric NaFeAs revealed by single-crystal 23Na,75As-NMR experiments
Kentaro Kitagawa, Yuji Mezaki, Kazuyuki Matsubayashi +2
We report results of 23Na and 75As nuclear magnetic resonance (NMR) experiments on a self-flux grown high-quality single crystal of stoichiometric NaFeAs. The NMR spectra revealed…
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…
Microwave Surface Impedance Measurements of LiFeAs Single Crystals
Yoshinori Imai, Hideyuki Takahashi, Kentaro Kitagawa +6
We report results of microwave surface impedance measurements of LiFeAs single crystals. The in-plane penetration depth depends on temperature exponentially at low temperatures, wh…
Pressure-induced changes in the magnetic and valence state of EuFe2As2
K. Matsubayashi, K. Munakata, N. Katayama +9
We present the results of electrical resistivity, ac specific heat, magnetic susceptibility, X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) of the…
Magnetic ordering and dense Kondo behaviour in EuFeP
Chunmu Feng, Zhi Ren, Shenggao Xu +6
Ternary iron phosphide EuFeP with ThCrSi-type structure has been systematically studied by the measurements of crystal structure, magnetization, Mössbauer effect, t…
