Popis: | The thermomagnetic properties of chromium sulfide CrS 1.17 were studied. The spontaneous magnetization of this compound, which is probably of the ferrimagnetic origin, suddenly disappears during cooling at -120°C. A slight heat absorption was observed at this transition point. By X-ray analysis excess diffraction lines besides those of the ideal crystal lattice of the nickel arsenide type were observed at room temperature, which shows a super-lattice structure with parameters of twice c and \(2\sqrt{3}\) times of a , a and c being those of the original lattice. It was also found by X-ray analysis that there was no change of the crystal lattice at the magnetic transition temperature, -120°C. This compound showed a ferrimagnetic behavior with the asymptotic Curie temperature at 150°K. A peak in susceptibility vs . temperature curve was found by the thermomagnetic measurement in the temperature range from the liquid helium temperature to -120°C. Basing on these data, a short discussion on the nature of the a... |
