Abstract

The perovskite-type oxides, GdxEu1−xCoO3 and HoxEu1−xCoO3 were prepared by the thermal decompositions GdxEu1−x[Co(CN)6]·4H2O and HoxEu1−x[Co(CN)6]·4H2O, respectively. GdxEu1−xCoO3 and HoxEu1−xCoO3 were orthorhombic and Pnma. In the ranges of 0≤x≤1, their lattice parameters of α-axis linearly lengthen with the increase of the value of x, but those of b and c axes decrease with the increase of x.

The magnetic susceptibility of EuCoO3 showed a typical Van Vleck paramagnetic property. The Co3+ ions in EuCoO3 were in the low spin state (t 62g e 0g , S=0), therefore the susceptibility of EuCoO3 was dependent on the Eu3+ ions in the temperature range from 5 to 300 K. Similarly, the Co3+ ions in GdxEu1−xCoO3 and HoxEu1−xCoO3 were also in the low spin state (t 62g e 0g , S=0), therefore the susceptibilities of GdxEu1−xCoO3 and HoxEu1−xCoO3 were dependent on the component of the Eu3+, Gd3+ and Ho3+ ions in the temperature ranges from 5 to 300 K.
