This quantity features a number of articles facing the physics and fabrics technology of normally metal infrequent earth fabrics. Chapters take care of the formation of amorphous, microcrystalline and quasicrystalline stages via mechanical alloying, speedy solidification or even general casting operations. As is usually the case with those 4f components, magnetism is a dominant subject and this is often mirrored within the chapters protecting floor magnetism, electron-spin resonance, alternate coupling in lanthanide-transition steel stages and the magnetic habit of ternary rare-earth stannides, together with their crystal buildings.
