| 内容記述 | Large perpendicular magnetic anisotropy (PMA), high spin polarization at the Fermi level, and a low Gilbert damping constant are the crucial properties of magnetic thin films for developing high density fast switching magnetic random-access memory (MRAM). Whilst ferromagnetic materials can show high spin polarization and large PMA, they are also sensitive to stray fields which can influence their performance in spintronic devices. Ferrimagnetic materials, specifically those which demonstrate a partially to fully compensated magnetic moment, are not only insensitive to stray field effects but also possess extremely low Gilbert damping constants around the compensation temperature. The first demonstration of a fully compensated ferrimagnetic material was in the full-Heusler Mn2RuGa (MRG) compound. However, MRG thin films suffer from problems such as thickness dependency and relatively low spin polarization, and therefore there has been a push to explore a wider range of Mn2YZ Heusler alloys to find the optimal ferrimagnetic material for MRAM applications |
