Web20 mei 2010 · Microwave assisted magnetic recording (MAMR) has recently emerged as a candidate to solve the trilemma in magnetic recording. In MAMR the magnetizations of recording medium can be switched with much lower magnetic field by magnetic resonance, which however requires a higher frequency oscillator than 20 GHz. In this … Web15 mrt. 2024 · The Toshiba researchers applied a bias current, an initial direct current voltage, to the STO, to induce the magnetisation oscillation needed to produce a microwave magnetic field and cause the magnetisation switching effect. They found that the average magnetisation direction of the spin torque oscillation modified the recording field.
