Temperature dependence of interlayer coupling in perpendicular magnetic tunnel junctions with GdOx barriers
Perpendicular magnetic tunnel junctions with GdOX tunneling barriers have shown a unique voltage controllable interlayer magnetic coupling effect. Here we investigate the quality of the GdOX barrier and the coupling mechanism in these junctions by examining the temperature dependence of the tunneling magnetoresistance and the interlayer coupling from room temperature down to 11 K. The barrier i...
متن کاملInterlayer perpendicular domain coupling between thin Fe films and garnet single-crystal underlayers
The magnetic behavior and domain structure of Fe films grown on yttrium–iron–garnet ~YIG! underlayers were studied to elucidate their interlayer coupling, as a function of the Fe layer thickness, using magnetic force microscopy ~MFM! and magneto-optic Kerr effect ~MOKE!. The YIG layer, grown by liquid phase epitaxy on single crystal gadolinium–gallium–garnet ~GGG! substrates, showed a character...
متن کاملInterlayer Exchange Coupling
The extensive research done on interlayer exchange coupling in transition metal multilayers has resulted in a deep understanding of this coupling and a remarkable agreement between theoretical results and measurements. The coupling between two magnetic layers separated by a non-magnetic spacer layer is mediated by the electrons of the spacer layer. The coupling, which oscillates in sign as a fu...
متن کاملInterfacial Co nanolayers for enhancing interlayer exchange coupling in antiferromagnetic interlayer exchange coupling media
Significant enhancement of the interlayer coupling strength has been achieved by depositing Co nanolayers on both sides of the Ru layer in a conventional CoCrPt/Ru/CoCrPt antiferromagnetic interlayer exchange coupling structure. The interlayer coupling increases nearly linearly from 0.13 to 0.8 erg/cm and then levels off with an increase in Co thickness. Substrate bias was found to be very harm...
متن کاملOscillatory interlayer exchange coupling and its temperature dependence in [Pt/Co]3/NiO/[Co/Pt]3 multilayers with perpendicular anisotropy.
Interlayer exchange coupling that oscillates between antiferromagnetic and ferromagnetic as a function of NiO thickness has been observed in [Pt(5 A)/Co(4 A)](3)/NiO(t(NiO) A)/[Co(4 A)/Pt(5 A)](3) multilayers with out-of-plane anisotropy. The period of oscillation corresponds to approximately 2 monolayers of NiO. This oscillatory behavior is possibly attributed to the antiferromagnetic ordering...
