Title

Structure of a spin-flop phase in the Weyl semimetal EuCuAs

Abstract

EuCuAs hosts magnetically-induced Weyl fermions whose band topology depends on the magnetic structure. In zero field the magnetic structure is a transverse helix with propagation vector (0, 0, 0.41). The aim of the proposal is to measure the magnetic structure in a spin-flop phase which is stable for magnetic fields H > H1 applied perpendicular to the c-axis, where H1 = 0.3T at T = 2K. We wish to measure the magnetic structure of the spin-flop phase in order to identify the magnetic interactions which stabilize the zero-field helix. We plan to collect magnetic reflections as a function of field applied by a vertical field magnet.
