Relaxation of thermo-remanent magnetization in Fe-Cr GMR multilayers

, 2005
The time decay of the thermo-remanent magnetization (TRM) in Fe-Cr giant magnetoresistive (GMR) multilayers has been investigated. The magnetization in these multilayers relaxes as a function of time after being cooled in a small magnetic field of 100 Oe

Flexible transparent graphene/polymer multilayers for efficient electromagnetic field absorption

Scientific Reports, 2014
Thanks to its high electrical conductivity, a graphene plane presents a good shielding efficiency against GHz electromagnetic radiations. Several graphene planes separated by thin polymer spacers add their conductivities arithmetically, because each of ...

Role of heterostructures and multiple magnetic phases in the low-field magnetization of Fe-Cr GMR multilayers

, 2005
Zero-field-cooled (ZFC) and field-cooled (FC) magnetization along with ac-magnetization vs. temperature and m-h loop measurements are reported for two series of ion-beam sputtered Fe-Cr GMR multilayers where the interface roughness is different.

Studies of Effects of Current on Exchange-Bias: A Brief Review

, 2008
MacDonald and co-workers recently predicted that high current densities could affect the magnetic order of antiferromagnetic (AFM) multilayers, in ways similar to those that occur in ferromagnetic (F) multilayers, and that changes in AFM magnetic order ...
