Magnetic field effect on the superconducting magnetic gap of Nd{1.85}Ce{0.15}CuO4

Abstract

Inelastic neutron scattering measurements on the archetypical electron-doped material Nd{1.85}Ce{0.15}CuO4 up to high relative magnetic field strength, H/Hc2 ~ 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 Hc2, and the high-field response resembles that of the paramagnetic normal state.
