We investigated an influence of substituting Sc for Mn sites on the charge and orbital ordered (CO/OO) state in Nd0.5Ca0.5MnO3. In the 3% Sc-doped sample, it is found that a magnetic susceptibility curve shows an anomalous cusp around 60 K on cooling. Electron diffraction measurement revealed that an incommensurate (IC) to commensurate (C) structural phase transition takes place around 60 K on cooling and it has a large thermal hysteresis. Furthermore, real space image in the IC phase by electron microscopy shows the presence of the discommensurastions with a phase slip of π.
