    Features of structural transitions in Ca2-xSmxMnO4 have been investigated by means of electron diffraction. When the temperature is lowered from a high-temperature tetragonal (HTT) phase in x = 0.3, there are successive transitions from the HTT phase to a low-temperature orthorhombic (LTO) one at 300 K and further to a low-temperature tetragonal (LTT) one at 100 K. In electron diffraction patterns, satellite spots with q ̄ = 1 8〈110〉 also appear below about 290 K. Features of the satellite spot arc that it is observed in 0.1 ≤ x ≤ 0.35 and its location depends on x.
