Interplay of antiferromagnetism, ferromagnetism and superconductivity in EuFe_2(As_1-xP_x)_2 single crystals
H. S. Jeevan, Deepa Kasinathan, Helge Rosner +1
We report a systematic study on the influence of antiferromagnetic and ferromagnetic phases of Eu^2+ moments on the superconducting phase upon doping the As site by isovalent P, wh…
Optical investigations of the chemical pressurized EuFe2(As1-xPx)2: an s-wave superconductor with strong interband interaction
D. Wu, G. Chanda, H. S. Jeevan +2
Superconducting EuFe2(As0.82P0.18)2 single crystals are investigated by infrared spectroscopy in a wide frequency range. Below Tc=28K a superconducting gap forms at 2Δ_{0} = 9.5 me…
High-resolution alternating-field technique to determine the magnetocaloric effect of metals down to very low temperatures
Yoshi Tokiwa, Philipp Gegenwart
The magnetocaloric effect or "magnetic Grüneisen ratio" quantifies the cooling or heating of a material when an applied magnetic field is changed under adiaba…
Electron-phonon coupling and momentum-dependent electron dynamics in EuFe2As2 using time- and angle-resolved photoemission spectroscopy
L. Rettig, R. Cortés, S. Thirupathaiah +7
The Fe pnictide parent compound EuFe2As2 exhibits a strongly momentum dependent carrier dynamics around the hole pocket at the center of the Brillouin zone. The very different dyna…
Dissimilarities between the electronic structure of chemically doped and chemically pressurized iron pnictides from an angle-resolved photoemission spectroscopy study
S. Thirupathaiah, E. D. L. Rienks, H. S. Jeevan +11
We have studied the electronic structure of EuFe2As2-xPx using high resolution angle-resolved photoemission spectroscopy. Upon substituting As with the isovalent P, which leads to…
Antiferromagnetic Mott insulating state in single crystals of the hexagonal lattice material Na2IrO3
Yogesh Singh, P. Gegenwart
We have synthesized single crystals of Na_2IrO_3 and studied their structure, transport, magnetic, and thermal properties using powder x-ray diffraction (PXRD), electrical resistiv…
