The superconductor KxSr(1-x)Fe2As2: Normal state and superconducting properties
B. Lv, M. Gooch, B. Lorenz +3
The normal state and superconducting properties are investigated in the phase diagram of K_xSr_{1-x}Fe_2As_2 for 0<x<1. The ground state upper critical field, H_{c2}(0), is extrapo…
Plasma-Like Negative Capacitance in Nano-Colloids
J. Shulman, S. Tsui, F. Chen +2
A negative capacitance has been observed in a nano-colloid between 0.1 and 10^-5 Hz. The response is linear over a broad range of conditions. The low-omega dispersions of both the…
A negative dielectric constant in nano-particle materials under an electric field at very low frequencies
C. W. Chu, F. Chen, J. Shulman +4
The significance of a negative dielectric constant has long been recognized. We report here the observation of a field-induced large negative dielectric constant of aggregates of o…
Suppression of Superconductivity in YBCO/LCMO Superlattices
F. Chen, B. Gorshunov, G. Cristiani +2
The competition of superconductivity and magnetism in superlattices composed of alternating YBaCuO and LaCaMnO thin films is investigated us…
Separation Between Antiferromagnetic and Ferromagnetic Transitions in Ru_1-xCu_xSr_2EuCu_2O_8+d
Y. Y. Xue, F. Chen, J. Cmaidalka +2
The macroscopic magnetizations of Ru_1-xCu_xSr_2EuCu_2O_8+d with x between 0 and 0.15 were investigated. A ferromagnet-like transition as well as an antiferromagnet-like transition…
