Magnetic and superconducting anisotropy in Ni-doped RbEuFeAs single crystals
K. Willa, M. P. Smylie, Y. Simsek +5
We investigate the effect of Ni doping on the Fe-site in single crystals of the magnetic superconductor RbEuFeAs for doping concentrations of up to 4%. A clear suppression…
Raman scattering study of lattice and magnetic excitations in CrAs
K. Sen, Y. Yao, R. Heid +6
We report on the lattice and spin dynamics in the monopnictide CrAs using polarized Raman scattering. This system exhibits a first-order magneto-structural phase transition at T_N~…
Melting of vortex lattice in magnetic superconductor
A. E. Koshelev, K. Willa, R. Willa +6
The iron-based superconductors are characterized by strong fluctuations due to high transition temperatures and small coherence lengths. We investigate fluctuation behavior in the…
Phase transition preceding magnetic long-range order in the double perovskite Ba2NaOsO6
Kristin Willa, Roland Willa, Ulrich Welp +4
Recent theoretical studies [Chen et al., Phys. Rev. B 82, 174440 (2010), Ishizuka et al., Phys. Rev. B 90, 184422 (2014)] for the magnetic Mott insulator Ba2NaOsO6 have proposed a…
Anisotropic upper critical field of pristine and proton-irradiated single crystals of the magnetically ordered superconductor RbEuFeAs
M. P. Smylie, A. E. Koshelev, K. Willa +12
We present a study of the upper critical field, H, of pristine and proton-irradiated RbEuFeAs crystals in pulsed magnetic fields of up to 65 T. The data for H…
