The rare-earth iron magnets are indispensable components in a vast range of electronic and electromechanical devices. This book covers the principles of Reviews: 2. A survey is given of the composition and crystal structure of existing rare earth transition intermetallics.
The relationship in crystal structure of the compounds RM 2, RM 3, R 2 M 7, RM 5, and R 2 M 17 is briefly discussed (R and M represent a rare earth and 3d element, respectively).
The variation of the magnetic moment of the M atoms and the variation of the Curie temperature brought about. The magnetocaloric effect (MCE) in many rare earth (RE) based intermetallic compounds has been extensively investigated during the last two decades, not only due to their potential applications for magnetic refrigeration but also for better understanding of the fundamental problems of the paper reviews our recent progress on studying the magnetic properties and MCE in.
The results obtained in this investigation have been used, together with those of other previously studied rare earth–Zn systems, to predict the constitutional properties of the Tb–Zn and Ho–Zn systems, taking into account that the alloying behaviour of the different rare earths with the same element varies according to systematic patterns.
The dehydrogenation of propanol has been studied in the range – K in the presence of hydride-forming rare-earth intermetallics R 2 Co 7 (R = Pr, Nd and Sm). The use of these hydride-forming compounds is advantageous in the dehydrogenation reaction under mild conditions, since the formation of metal hydrides can change the unfavourable equilibrium in favour of dehydrogenation.
