| 中文摘要 | The effects of La-doping and external pressure on the crystal structure of layered perovskite-like manganate Ca3Mn2O7 have been investigated by substituting La3+ for Ca2+ in Ca3Mn2O7 and in situ high pressure energy dispersive X-ray diffraction measurements on Ca3Mn2O7, respectively. With the increase of La3+ content in compounds with nominal compositions, La2-2xCa1+2xMn2O7 (x = 1.0-0.5), single-phase compounds with a tetragonal structure are formed only in the range x = 1.0-0.6 and the lattice parameter a increases with increasing La-doping level while c decreases. Similarly, with the increase of external pressure in the range 0-1.3 GPa, the lattice parameter a of the layered perovskite manganate Ca3Mn2O7 increases while c decreases, and the structure of Ca3Mn2O7 undergoes a phase transition from a tetragonal to a orthorhombic structure at about 1.3 GPa. The La-doping and external pressures have the same effect on the lattice structure of the layered perovskite manganate Ca3Mn2O7. |
