Lattice dynamics of KNi2Se2

N. Lazarević, M. Radonjić, M. Šćepanović +4

We report the first principle calculations of the lattice dynamics of KNi $_{2}$ Se $_{2}$ together with the Raman scattering study.\ We have observed three out of four Raman active mod…

Evidence of superconductivity-induced phonon spectra renormalization in alkali-doped iron selenides

M. Opačić, N. Lazarević, M. Šćepanović +4

Polarized Raman scattering spectra of superconducting K $_{x}$ Fe $_{2 - y}$ Se $_{2}$ and nonsuperconducting K $_{0.8}$ Fe $_{1.8}$ Co $_{0.2}$ Se $_{2}$ single crystals were measured in a temperatur…

Charge density wave modulation and gap measurements in CeTe $_{3}$

Uros Ralevic, Nenad Lazarevic, Andreas Baum +7

We present a study of charge density wave (CDW) ordering in CeTe $_{3}$ at room temperature using a scanning tunneling microscope and Raman spectroscopy. Two characteristic CDW orderi…

Raman spectroscopy of K_xCo_{2-y}Se_2 single crystals near the ferromagnet-paramagnet transition

M. Opačić, N. Lazarević, M. M. Radonjić +6

Polarized Raman scattering spectra of the K_xCo_{2-y}Se_2 single crystals reveal the presence of two phonon modes, assigned as of the A_{1g} and B_{1g} symmetry. Absence of additio…

Insulating and metallic spin glass in K $_{x}$ Fe $_{2 - δ - y}$ Ni $_{y}$ Se $_{2}$ (0.06 $\leq$ $y$ $\leq$ 1.44) single crystals

Hyejin Ryu, Milinda Abeykoon, Kefeng Wang +6

We report electron doping effects by Ni in K $_{x}$ Fe $_{2 - δ - y}$ Ni $_{y}$ Se $_{2}$ (0.06 $\leq$ $y$ $\leq$ 1.44) single crystal alloys. A rich ground state phase diagram is observed. S…

Sustained phase separation and spin glass in Co-doped K $_{x}$ Fe $_{2 - y}$ Se $_{2}$ single crystals

Hyejin Ryu, Kefeng Wang, M. Opacic +5

We present Co substitution effects in K $_{x}$ Fe $_{2 - y - z}$ Co $_{z}$ Se $_{2}$ (0.06 $\leq$ $z$ $\leq$ 1.73) single crystal alloys. By 3.5\% of Co doping superconductivity is suppressed…
