The effects of the HDDR (hydrogenation decomposition desorption recombination) phenomenon on the magnetic properties of SmFe11Ti, SmFe10MM′, NdFe11Ti, and Nd1+δFe10MM′ (δ=0, 0.3, M=Ti, V, Mo, M′=V, Mo) compounds with ThMn12-type Structure were investigated. Alloy powders of SmFe10V2, SmFe10TiV, and NdFe10MM′; (M=Ti, V, Mo, M′;=V, Mo) form a ThMn12-type structure after heat treatment at 800°C in hydrogen and subsequently in a vacuum, but RFe11Ti (R=Sm, Nd) compounds form a TbCu7-type structure. High coercivities of 6.0 kOe and 5.8 kOe were obtained with SmFe10TiV and Nd1.3Fe10VMoNx compounds subjected to the HDDR Phenomena, respectively.
