چکیده انگلیسی
Al-doped B4C was synthesized by high temperature solid-state sintering of carbon, boron and aluminum powders at 2200 °C. Results of X-ray diffraction and Raman spectroscopy of the products revealed that the Al atoms had entered the B4C lattice. The AC susceptibilities of Al-doped B4C which measured at different frequencies exhibited temperature-dependence. And the freezing temperatures shifted to higher value as the driving frequency increased. The finding was consistent with the features of a canonical spin glass. It consequently demonstrated that our prepared Al-doped B4C sample was a spin glass system.
