We employed Raman spectroscopy to investigate how the hydrostatic pressure affects the temperature of the Verwey transition in pure (Fe3O4) and Al-doped (Fe2.8Al0.2O4) magnetite. In both samples, pressure suppresses the transition. The Al-doped sample disp ...
Since the discovery of cuprate superconductors in 1986, the subject of high temperature superconductivity has triggered a lot of scientific activity. Despite enormous efforts, the origin of high-temperature superconductivity is still the subject of intense ...
The Hall coefficient RH of the cuprate superconductor YBa 2Cu3Oy was measured in magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152 in the underdoped regime. In fields large enough to suppress superconductivity, RH(T) is seen to go f ...
We use small-angle neutron scattering to study the superconducting vortex lattice in La2−xSrxCuO4 as a function of doping and magnetic field. We show that near optimally doping the vortex lattice coordination and the superconducting coherence length ξ are ...
The thermal conductivity κ of the iron-arsenide superconductor LiFeAs (Tc 18 K) was measured in single crystals at temperatures down to T50 mK and in magnetic fields up to H=17 T, very close to the upper critical field Hc218 T. For both directions of the h ...
This study presents the mechanical characterization of the dry film photoresist PerMX and its adhesion properties when laminated onto Kapton (R) E (PI) and Melinex (R) ST506 (PET). Additionally, the processing temperature, the adhesion strength, and the ne ...
The iron-pnictide superconductors have a layered structure formed by stacks of FeAs planes from which the superconductivity originates. Given the multiband and quasi three-dimensional(1) (3D) electronic structure of these high-temperature superconductors, ...
The Nernst coefficient of the cuprate superconductor YBa2Cu 3Oy was recently shown to become strongly anisotropic within the basal plane when cooled below the pseudogap temperature T, revealing that the pseudogap phase breaks the fourfold rotational symmet ...
It is still unclear why the transition temperature Tc of cuprate superconductors falls with underdoping. The doping dependence of the critical magnetic field Hc2 is directly relevant to this question, but different estimates of Hc2 are in sharp contradicti ...
We present an angle-resolved photoelectron spectroscopy study of YBa2Cu3O7-delta films in situ grown by pulsed laser deposition. We have successfully produced underdoped surfaces with ordered oxygen vacancies within the CuO chains resulting in a clear orth ...
