Interlayer coupling induced quasiparticles

Interlayer 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...

Interlayer coupling through a dimensionality-induced magnetic state

Dimensionality is known to play an important role in many compounds for which ultrathin layers can behave very differently from the bulk. This is especially true for the paramagnetic metal LaNiO3, which can become insulating and magnetic when only a few monolayers thick. We show here that an induced antiferromagnetic order can be stabilized in the [111] direction by interfacial coupling to the ...

Interfacial 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...

Vortex fluctuations and interlayer coupling in cuprates.

The reversible magnetization (M ) curves of HgBa2Cam21CumO2m121d ~m51, 2, and 3! at different H cross at a temperature T* and M5M* as suggested by various two-dimensional ~2D! vortex-fluctuation models. However, the obtained M*/T* was found to be independent of either m or the sheet density 1/s of the CuO2 blocks, where s is the size of the unit cell along the c axis, in contrast to the predict...
