Temperature dependence of interlayer exchange coupling. - In: Journal of magnetism and magnetic materials, ISSN 1873-4766, Bd. 310.2007, 2, Pt. 3, S. 2301-2303
We use a microscopic model for ultrathin metallic films to analyze temperature dependent FMR measurements of exchange coupled NiCo films. The reduction of the interlayer exchange coupling with increasing temperature is investigated. We find that magnon excitations are the dominating cause of the temperature dependence.

Quantum mechanical calculations based on an extended Heisenberg model are ompared with ferromagnetic resonance experiments on prototype trilayer systems Ni7/Cun/Co2/Cu(001)in order to determine and separate for the first time quantitatively the sources of the temperature dependence of interlayer exchange coupling. Magnon excitations are responsible for about 75% of the reduction of the coupling strength from zero to room temperature. The remaining 25% are due to temperature effects in the effective quantum well and the spacer-magnet interfaces.
