Enhancement of magnetic order in the incommensurate phase of Mg-doped CuGeO${}_3$

C. Stock, S. Wakimoto, R. J. Birgeneau +4

We present elastic neutron scattering results at high magnetic fields for Mg-doped CuGeO${}_3$. For low magnesium concentrations, where a spin-Peierls phase is present, we find an…
