Figure 3
The (a) c lattice parameter and (b) a lattice parameters as a function of temperature for an LNT94 powder sample. In (b), the black line gives a linear fit to the data, and the residual of this fit is plotted in (c). The data above the Curie point are red and have been fitted with a second-order polynomial in (a) and (c), below the Curie point the points are black and are fitted by a fourth-order polynomial in (a) and (c).
