Abstract :
The experimental investigations of the FMR frequency-field dependences at room temperature T=300 K and temperature of liquid nitrogen T=77K for the substituted sample of strontium hexaferrite SrFe11.2Al0.8O19 are presented. It is shown, that with decrease of temperature the difference dHhys between the field of saturation Hsat and the field of breaking Hbr (dHhys=Hsat - Hbr) is changed insignificantly.
