Superconductivity in single-crystal

Synthesis and Superconductivity of Electrochemically Grown Single-Crystal Aluminum Nanowires

Superconducting systems with one or more physical dimensions smaller than the phase coherence length (ξ(T)) exhibit behavior different from bulk superconductors. 1 These quasi-two-dimensional (2D) or one-dimensional (1D) systems are a subject of great interest both for fundamental physics and potential technological applications. Aluminum nanowires (ANW) have been a favorite candidate for study...

Coexistence of superconductivity (Tc= 55 K) and antiferromagnetism TN= 230 K) in YBa2CuS06. 66 single crystal

2014 Neutron scattering and susceptibility measurements on a YBa2CU3O6.55 single crystal show that the antiferromagnetic long range order coexists with superconductivity. The oxygen content has been determined by a complete neutron diffraction structure analysis. Evidence for superconductivity below Tc= 55 K has been obtained from magnetization measurements. Magnetic Bragg scattering has been o...

Calorimetric evidence of strong-coupling multiband superconductivity in Fe(Te0.57Se0.43) single crystal

Magneto-Optical properties of GaP single crystal

The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...

Superconductivity in single crystals of LaFePO

Single crystals of the compound LaFePO were prepared using a flux growth technique at high temperatures. Electrical resistivity measurements reveal metallic behavior and a resistive transition to the superconducting state at a critical temperature Tc ∼ 6.6 K. Magnetization measurements also show the onset of superconductivity near 6 K. In contrast, specific heat measurements manifest no discont...
