The effective write field of microwave assisted magnetic recording (MAMR) was investigated using the Landau Lifshitz Gilbert (LLG) simulation and an analytical method. An effective component of high frequency (HF) field was obtained by considering the angle between the magnetization of recording media and the HF field generated from field generation layer (FGL). An analytical method to obtain the effective write field was proposed by using the switching properties of the recording medium graphically. The obtained effective write field has shown that the value of the maximal effective field gradient of 1850 Oe/nm is three times larger than that for Stoner-Wohlfarth effective write field.
