Giant magnetoresistance in intermetallics

IEEE Transactions on Magnetics, 1996
Some typical examples of large magnetoresistance effects observed in intermetallic compounds are reviewed and briefly compared with the giant magnetoresistance (GMR) of magnetic multilayers. Basically, the large magnetoresistance changes are observed at metamagnetic transitions in two classes of intermetallics, antiferromagnetics and spin fluctuators ...

Powder processing of intermetallic alloys and intermetallic matrix composites

Materials Science and Engineering: A, 1991
Abstract This presentation covers the use of powder metallurgy for the formation of monolithic intermetallics and intermetallic matrix composites. A notable development has been the fabrication of homogeneous high density compacts from elemental powders by reactive sintering. A variant process involving simulataneous pressurization in a hot isostatic
