CoxTi1−xO2−δ films have been prepared on Si(001) substrates by sol–gel method. When heat treated in air, CoxTi1−xO2−δ films are non-ferromagnetic at room temperature. However, after further vacuum annealing or hydrogenation, CoxTi1−xO2

We have studied the zero-field hyperfine splitting of in ferrimagnetic (x = 1, 1.5, 2) using spin-echo NMR at 4.2 K. Distinct spectra arising from the different sites characterized by the numbers of carbon nearest neighbours (NN = 0, 1, 2, 3) are obs

The structure and magnetic properties of Sm2Fe17−xGaxC2.5 (x = 2, 3, 4 and 5) compounds prepared by arc-melting were studied. X-ray diffraction shows that these samples are single phase with rhombohedral Th2Zn17-type structure. The unit-cell volume

The formation, structure and magnetic properties of (Er1 − xYx)2Fe17C2 (0 ⩽ x ⩽ 1.0) prepared by melt spinning were studied. Arc-melted (Er1 − xYx)2Fe17C2 alloys are found to have a two-phase structure with the 2:17 phase and a predominant α

The compound Er2Fe17C2.5 formed by melt spinning has the rhombohedral Th2Zn17-type structure. The spin reorientation transition occurs at about 136 K. The 57Fe Mossbauer effect was measured in the temperature range 12-300 K. From the acceptable fit t
