Ma. Wongsam et Rw. Chantrell, THERMAL-ACTIVATION OF SPIN-WAVE MODES IN CO BASED MULTILAYERS, IEEE transactions on magnetics, 34(4), 1998, pp. 1330-1332
An extension of the micromagnetic fluctuation theory is used to model
the thermal excitations of spin wave modes in Co based magnetic/non-ma
gnetic (M/NM) multilayers. Results are obtained for samples with conti
nuous and granular magnetic layers, clearly demonstrating thermal exci
tations of increasing amplitude and involving higher frequencies as th
e temperature is increased. Also, the response is greater at lower val
ues of the external field.
