High coercivity values in the range of MA m-1 were observed at low temperatures for amorphous ribbons. Presence of Fe-rich clusters and nanoscale rare-earth crystallites in the amorphous matrix in the ribbons were revealed by high-resolution transmission electron microscopy studies. The magnetic transition temperatures were estimated experimentally and compared with fitting results based on the cluster ferromagnetism model (Wang L et al 2001 Phys. Rev. B 64 214410). Possible mechanisms for the magnetic behaviour observed due to the presence of Fe-rich magnetic clusters are discussed.||Source Title:||Journal of Physics D: Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/107146||ISSN:||00223727||DOI:||10.1088/0022-3727/35/5/302|
