Inelastic neutron-scattering measurements on the archetypical electron-doped material Nd1.85Ce0.15CuO4 up to a high relative magnetic-field strength, H/H(c2) approximately 50%, reveal a simple linear magnetic-field effect on the superconducting magnetic gap and the absence of field-induced in-gap states. The extrapolated gap-closing field value is consistent with the upper critical field H(c2), and the high-field response resembles that of the paramagnetic normal state. 

Post-growth annealing effects on charge and spin excitations in Nd2−xCexCuO4

We report a Cu K- and L$_3$-edge resonant inelastic x-ray scattering study of charge and spin excitations of bulk Nd$_{2-x}$Ce$_x$CuO$_4$, with focus on post-growth annealing effects. For the parent

Magnetic Field-Induced Closure of the Spin Excitation Gap near Optimal Doping in La2-xSrxCuO4

We have investigated how a magnetic field applied perpendicular to the CuO2 planes of the near-optimally hole-doped high-temperature superconductor La1.855Sr0.145CuO4 (Tc ≈36 K) influences the

Evolution of the Spin Resonance of CeCoIn5as a Function of Magnetic Field and La Substitution

We report the evolution of the spin resonance in CeCoIn 5 as a function of magnetic field and lanthanum substitution. In both cases, the resonance peak position shifts to lower energy and the

Ferromagnetic signal and unconventional Kondo-like effect in the superconducting Y1−xPrxBa2Cu3O7−δ systems

Electrical and magnetic properties were studied for the Y1−xPrxBa2Cu3O7−δ superconductors with x=0.44–0.48, which was located near the antiferromagnetic (AFM) and superconducting (SC) phase

Spectroscopic Evidence for Competing Order-Induced Pseudogap Phenomena and Unconventional Low-Energy Excitations in High-Tc Cuprate Superconductors

AbstractThe low-energy excitations of cuprate superconductors exhibit various characteristics that differ from those of simple Bogoliubov quasiparticles for pure $d_{x^{2}-y^{2}}$ -wave

Progress and perspectives on electron-doped cuprates

Although the vast majority of high-$T_c$ cuprate superconductors are hole-doped, a small family of electron-doped compounds exists. Under investigated until recently, there has been tremendous recent

Effects of d-wave pairing in n-type high-temperature superconductors with anisotropic impurity scattering

AbstractThe temperature dependences of the resistivity of single-crystal films of the Nd2 − xCexCuO4 + δn-type superconductors with x = 0.14 (underdoped region) and x = 0.15 (optimal doping region)

Effect of strong correlations on the high energy anomaly in hole- and electron-doped high-Tc superconductors

Recently, angle-resolved photoemission spectroscopy (ARPES) has been used to highlight an anomalously large band renormalization at high binding energies in cuprate superconductors: the high energy
