Bandwidth controlled insulator-metal transition in BaFeS: A Mössbauer study under pressure
Philipp Materne, Wenli Bi, Jiyong Zhao +6
BaFeS is a quasi one-dimensional Mott insulator that orders antiferromagnetically below 117(5)\,K. The application of pressure induces a transition to a metallic state, and…
Microscopic phase diagram of LaFeAsO single crystals under pressure
Philipp Materne, Wenli Bi, Jiyong Zhao +6
We investigated LaFeAsO single crystals by means of synchrotron Mössbauer spectroscopy under pressures up to 7.5 GPa and down to 13 K and provide a microscopic phase diagram. We fo…
Superconducting and magnetic phase diagram of RbEuFe4As4 and CsEuFe4As4 at high pressure
Daniel E. Jackson, Derrick VanGennep, Wenli Bi +7
The recently discovered (Rb,Cs)EuFe4As4 compounds exhibit an unusual combination of superconductivity (Tc = 35 K) and ferromagnetism (Tm = 15 K). We have performed a series of x-ra…
Suppression of the magnetic order in CeFeAsO: non-equivalence of hydrostatic and chemical pressure
Philipp Materne, Wenli Bi, Esen Ercan Alp +12
We present a detailed investigation of the electronic properties of CeFeAsO under chemical (As by P substitution) and hydrostatic pressure by means of in-house and synchrotron Möss…
Distinct pressure evolution of coupled nematic and magnetic order in FeSe
Anna E. Böhmer, Karunakar Kothapalli, Wageesha T. Jayasekara +13
FeSe, despite being the structurally simplest compound in the family of iron-based superconductors, shows an astoundingly rich interplay of physical phenomena including nematicity…
Pressure-induced superconductivity in elemental ytterbium metal
Jing Song, James S. Schilling
Ytterbium (Yb) metal is divalent and nonmagnetic but would be expected under sufficient pressure to become trivalent and magnetic. We have carried out electrical resistivity and ac…
