Coexistence of 3d-ferromagnetism and superconductivity in [(Li1-x Fex )OH](Fe1-y Liy )Se.
Superconducting [(Li1-x Fex )OH](Fe1-y Liy )Se (x≈0.2, y≈0.08) was synthesized by hydrothermal methods and characterized by single-crystal and powder X-ray diffraction. The structure contains alternating layers of anti-PbO type (Fe1-y Liy )Se and (Li1-x Fex )OH. Electrical resistivity and magnetic susceptibility measurements reveal superconductivity at 43 K. An anomaly in the diamagnetic shield...
متن کاملFerromagnetism and the Formation of Interlayer As2 Dimers in Ca(Fe1-xNix)2As2
Dedicated to Professor Heinrich Nöth on the occasion of his 85th birthday The compounds Ca(Fe1−xNix)2As2 with the tetragonal ThCr2Si2-type structure (space group I4/mmm) show a continuous transition of the interlayer As–As distances from a non-bonding state in CaFe2As2 (dAs−As = 313 pm) to single-bonded As2 dimers in CaNi2As2 (dAs−As = 260 pm). Magnetic measurements have revealed weak ferromagn...
متن کاملDirect observation of spontaneous weak ferromagnetism in the superconductor ErNi2B2C.
Neutron measurements show that superconducting ErNi2B2C (T(C) = 11 K) develops antiferromagnetic spin density wave magnetic order (T(N) = 6 K), which squares up with decreasing temperature yielding a series of higher-order magnetic Bragg peaks with odd harmonics. Below T(WFM) = 2.3 K where magnetization indicates a net moment develops, even-order Bragg peaks develop which low field (approximate...
متن کاملSuperconductivity on the border of weak itinerant ferromagnetism in UCoGe.
We report the coexistence of ferromagnetic order and superconductivity in UCoGe at ambient pressure. Magnetization measurements show that UCoGe is a weak ferromagnet with a Curie temperature T(C)=3 K and a small ordered moment m(0)=0.03 micro(B). Superconductivity is observed with a resistive transition temperature T(s)=0.8 K for the best sample. Thermal-expansion and specific-heat measurements...
متن کاملWeak d 0 ferromagnetism: Zn vacancy condensation in ZnS nanocrystals.
We provide the explanation of the large discrepancy of three orders of magnitude between the experimentally measured and theoretically calculated magnetic moments in ZnS nanocrystals. We assume that the condensation of Zn vacancies into a single droplet takes place. The energy calculations reveal that the droplet phase is more favorable than the uniformly distributed vacancy configuration. The ...
