the effects of Mg doping on the high-field incommensurate phase
of CuGeO3. Lorentzian-squared line shapes, the changing of the
first-order transition to second order, and the destruction of
long-range order with infinitesimal doping are observed,
consistent with random-field effects in a three-dimensional XY
system. Values for the soliton width in pure and lightly doped
CuGeO3 are deduced. We find that even a very small doping has a
drastic effect on the shape of the lattice modulation. | | External Publication Status: | published | | Document Type: | Article |
