Rare-earth transition metal carbides

The intrinsic magnetic properties of rare-earth transition-metal compounds have been found to improve dramatically with nitrogen and carbon additions which are made through the gas-phase interstitial modification proceess. In this work, we have obtained rare-earth transition metal carbides with the 2:17 and 1:12 structures using methane and ethane. They intrinsic magnetic properties of these compounds have been studied and the results will be reported.
