We propose a magnetic multilayer layout, in which the indirect exchange coupling (IEC also known as RKKY) can be switched on and off by a slight change in temperature. We demonstrate such on/off IEC switching in a Fe/Cr/FeCr-based system and obtain thermal switching widths as small as 10–20 K, essentially in any desired temperature range, including at or just above room temperature. These results add a new dimension of tunable thermal control to IEC in magnetic nanostructures, highly…

Tuning thermo-magnetic properties of dilute-ferromagnet multilayers using RKKY interaction

We demonstrate a 20-fold enhancement in the strength of the RKKY interlayer exchange in dilute-ferromagnet/normal-metal multilayers by incorporating ultrathin Fe layers at the interfaces.

Giant magnetocaloric effect driven by indirect exchange in magnetic multilayers

Indirect exchange coupling in magnetic multilayers, also known as the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, is known to be highly effective in controlling the interlayer alignment of the

Thermal Gating of Magnon Exchange in Magnetic Multilayers with Antiferromagnetic Spacers.

A strong thermally controlled magnon-mediated interlayer coupling of two ferromagnetic layers via an antiferromagnetic spacer in spin-valve type trilayers is observed, which can be controlled by varying temperature and the spacer thickness.

Magnetic Hysteresis in Nanostructures with Thermally Controlled RKKY Coupling

Theoretical analysis indicates that the measured step-like shape and hysteresis of the magnetization loops is due to local in-plane magnetic anisotropy of nano-crystallites within the strongly ferromagnetic films, which should help enable the practical use of RKKY for thermally switching the magnets in magnetic multilayers.

Inverse magnetocaloric effect in synthetic antiferromagnets

The magnetocaloric effect in exchange-coupled synthetic-antiferromagnet multilayers is investigated experimentally and theoretically. We observe a temperature-controlled inversion of the effect,

Spin relaxation in multilayers with synthetic ferrimagnets

We demonstrate the strong tunability of the spin-pumping contribution to magnetic damping in a thin-film ferromagnetic free layer interfacing with a synthetic ferrimagnet (SFM), acting as a spin si



Temperature-induced reversal of magnetic interlayer exchange coupling.

A temperature-induced sign reversal of IEC was observed for constant dY, arising from magnetization-dependent electron reflectivities at the magnetic interfaces, in addition to the expected oscillatory behavior as a function of spacer-layer thickness dY.

Temperature-controlled interlayer exchange coupling in strong/weak ferromagnetic multilayers : A thermomagnetic Curie switch

We investigate interlayer exchange coupling based on driving a strong/weak/strong ferromagnetic trilayer through the Curie point of the weakly ferromagnetic spacer, with exchange coupling between the

Layered magnetic structures: Evidence for antiferromagnetic coupling of Fe layers across Cr interlayers.

In small external fields such double layers order antiparallel with their magnetization perpendicular to the external field in analogy to the spin‐flop phase of antiferromagnets, revealed by the behavior of the static magnetization of such samples as a function of external field and the spectrum of spin‐wave modes with the wave vector parallel to a small external field.

Confinement mechanism for strong temperature dependence of the interlayer exchange coupling in Co/Cu(001).

It is shown that the existing theories fail to explain the observed J(T) because there is an additional mechanism of the temperature dependence of the interlayer exchange coupling which has not been considered in any of the previous theoretical treatments.

Giant magnetoresistance of (001)Fe/(001)Cr magnetic superlattices.

This work ascribes this giant magnetoresistance of (001)Fe/(001)Cr superlattices prepared by molecularbeam epitaxy to spin-dependent transmission of the conduction electrons between Fe layers through Cr layers.
