Abstract :
[en] The specific absorption rate (SAR) concept of hyperthermia ferrofluids is discussed. It is first
suggested that SAR can be characterized at the steady state condition, taking into account the
heating flow mechanism from the ferrofluid to the external environment. The temperature
dependence of SAR is then addressed, indicating that the influence arises from both magnetic
susceptibility and relaxation time of the system. At last, a single equation able to express the
temperature versus time profile of a ferrofluid, when SAR is virtually temperature independent, is proposed up to the equilibrium condition.
