Quenching of giant magnetoresistance by interface roughening and alloying in annealed [(NixFe1–x)yAu1–y]/Au multilayers
Antiferromagnetically coupled permalloy/Au multilayers display giant magnetoresistance (GMR) with large changes in resistance in very low fields. We show that thermal annealing of such structures, exh...

A simple fabrication method is described to produce reliable and robust (self-repairing) field emission sources from randomly aligned carbon nanotubes. The sources display stable and reproducible curr...

Strains of nearly 0.2% have been induced along [001] in unstressed crystals of Ni2MnGa with magnetic fields of 8 kOe applied at 265 K. These stains are associated with the superelastic motion of twin boundaries in the martensitic phase that is stable below about 274 K. ©1996 American Institute of Physics.
