✦ Synopsis

The effect of a polymer matrix on phase transitions in CuFe 2 O 4 spinel oxide has been studied. XRD results show that cubic CuFe 2 O 4 is obtained by quenching from 1173 K, while with CuFe 2 O 4 -PEEK composite samples, the cubic form is obtained by quenching from considerably lower temperatures (:733 K). The change in resistivity with temperature of the quenched composite samples shows that the cubic samples quenched from < 1173 K undergo several phase changes during heating. Measurements of thermoelectric power indicate that the composite samples quenched from 41073 K show n-type conduction, and the sample quenched from 1173 K shows p-type conduction.

Raman and IR studies of a single orthorhombic crystal and of polycrystalline trigonal RbIn(MoO 4 ) 2 were performed at ambient temperature. The observed vibrational modes were assigned to the respective motions of atoms in the unit cells. It was shown that the first-order D 3d 3 β†’ D 2h 16 phase tran
