In the pursuit of rare earth-lean permanent magnets for green technologies, microstructural optimisation offers a promising strategy to enhance coercivity while minimising critical element content. For this approach, the combination of experimental w

Ce-based R2Fe14B (R= rare-earth) nano-structured permanent magnets consisting of (Ce,Nd)2Fe14B core-shell grains separated by a non-magnetic grain boundary phase, in which the relative amount of Nd to Ce is higher in the shell of the magnetic grain t

The magnetically localized and wash-free fluorescence immunoassay (MLFIA) is a no-wash assay for directly measuring biomolecule (antigen and antibody) concentration, without mixing nor washing steps, from a body fluid (serum and plasma).

Bulk Fe/Pt multilayers were annealed to form hard magnetic L 1 0 FePt-based permanent magnet foils. The phase composition of the foils, and thus their magnetic properties, were found to depend not only on the temperature and time of annealing, but al

A comprehensive review on the use of swift heavy ion irradiation of intermetallic rare earth-transition metal compounds is given. We show that latent track precipitation is possible in some of these metallic compounds, with diameters in the range 1

Various processing routes for making permanent magnets based on interstitially modified Sm,Fe,, have been recently developed. Zn bonding of coarse grained Sm2Fe17N3 gives coercivities mu(0J)H(c) as high as 2.2 T. Effective methods to prepare highly c

Powders of Sm 2 Fe 17 (and other iron-rich rare earth intermetallics) which have been exposed to ambient air or treated in water are found to desorb hydrogen when heated above 250°C in vacuum or in a relatively inert gas such as N 2 . The source of

Coercivity has been developed in multi-domain Sm2Fe17N3 powders by irradiation with high energy Pb ions. Mossbauer measurements indicate that the effect of irradiation is to create extended defects of amorphous Sm-Fe-N. High values of ion fluence (

The production of interstitial permanent magnets, in particular bonded Sm2Fe17N3 magnets, is discussed. The key figure of merit of a permanent magnet is the energy product (BH)max, which describes the magnets ability to store energy. Starting from a
