Microwave Heating of Oxidized Iron Powders in Ferromagnetic Resonance Mode

By the example of α-Fe 2 O 3 hematite, 5Fe 2 O 3 ⋅9H 2 O ferrihydrite, and γ-Fe 2 O 3 maghemite powders, a microwave-radiation-induced powder system temperature growth Δ T max of several degrees has been measured in the ferromagnetic resonance mode at a frequency of 8.9 GHz. The powders heat up the...

Description
Summary:By the example of α-Fe 2 O 3 hematite, 5Fe 2 O 3 ⋅9H 2 O ferrihydrite, and γ-Fe 2 O 3 maghemite powders, a microwave-radiation-induced powder system temperature growth Δ T max of several degrees has been measured in the ferromagnetic resonance mode at a frequency of 8.9 GHz. The powders heat up the most in the external field H coinciding with the ferromagnetic resonance field. The value of the Δ T max effect depends on the magnetization of a powder material. The results obtained allow us to propose a new magnetic hyperthermia method for biomedical applications.
