Complex phase diagram of BaNaFeAs: a multitude of phases striving for the electronic entropy
Liran Wang, F. Hardy, A. Böhmer +3
The low-temperature electronic phase diagram of BaNaFeAs, obtained using high-resolution thermal-expansion and specific-heat measurements, is shown to be…
Fermi surface reconstruction in FeSe under high pressure
Taichi Terashima, Naoki Kikugawa, Andhika Kiswandhi +13
We report Shubnikov-de Haas (SdH) oscillation measurements on FeSe under high pressure up to = 16.1 kbar. We find a sudden change in SdH oscillations at the onset of the pressu…
Infrared study of the spin reorientation transition and its reversal in the superconducting state in underdoped BaKFeAs
Ben PP Mallett, Premysl Marsik, Meghdad Yazdi-Rizi +6
With infrared spectroscopy we investigated the spin-reorientation transition from an orthorhombic antiferromagnetic (o-AF) to a tetragonal AF (t-AF) phase and the reentrance of the…
Dichotomy between the hole and electrons behavior in the multiband FeSe probed by ultra high magnetic fields
M. D. Watson, T. Yamashita, S. Kasahara +15
Magnetoresistivity \r{ho}xx and Hall resistivity \r{ho}xy in ultra high magnetic fields up to 88T are measured down to 0.15K to clarify the multiband electronic structure in high-q…
Pressure-induced antiferromagnetic transition and phase diagram in FeSe
Taichi Terashima, Naoki Kikugawa, Shigeru Kasahara +9
We report measurements of resistance and ac magnetic susceptibility on FeSe single crystals under high pressure up to 27.2 kbar. The structural phase transition is quickly suppress…
Doping dependence of the critical fluctuation regime in the Fe-based superconductor BaKFeAs
Jianqiang Hou, Philipp Burger, Huen Kit Mak +4
We investigate the importance of superconducting order parameter fluctuations in the 122 family of Fe-based superconductors, using high-resolution specific heat and thermal expansi…
