The cation distribution has been determined in the nickel manganites NiMnzO, and Ni, sMnz zO, from powder neutron diffraction studies. It strongly depends upon the thermal history of the specimens. Additional information given by MnZt thermogravimetric oxidation experiments, has established the oxid
Four phase transitions at: T h C1 ΒΌ 267:1 K, T h C2 ΒΌ 258:8 K, T h C3 ΒΌ 254:1 K and T h C4 ΒΌ 195:4 K (on heating) and at T c C1 ΒΌ 263:8 K, T c C2 ΒΌ 255:4 K, T c C3 ΒΌ 246:0 K (on cooling) were determined for [Ca(H 2 O) 4 ](ClO 4 ) 2 between 90 and 295 K by means of differential scanning calorimetry
