Topic:

Static and dynamic magnetics in rare-earth iron garnets

Rare earth iron garnets (REIGs) are complex ferrimagnetic oxides known for their tunable magnetic properties. Coercivity, saturation magnetization, perpendicular magnetic anisotropy, temperature dependence, and Gilbert damping are just a few characteristics that can be altered via elemental substitution, strain, or growth conditions. These adjustable features make REIGs a leading material in spintronics devices, magnetic counterparts to traditional CMOS information storage and processing. In this talk, I will explain the magnetic benefits of REIGs and their promise in spintronics applications. In addition, their temperature dependent magnetic behavior will be discussed, including a python program I developed to model these complex materials. Then I will dive into their magnetization dynamics, specifically how magnons and domain walls interact to enable magnon-driven translation of domain walls in BiYIG, with the potential for high-speed memory or logic device designs. Throughout this talk, I will discuss challenges that emerged during these projects and the creative solutions we built or understandings we developed as a result. This project is funded through NSF.

Biography:

Miela Gross in the 4th year of her PhD in the electrical engineering and computer science department at MIT. Prior to MIT, she completed her bachelors in physics at UC Berkeley in 2020. She is originally from San Diego, CA and yes, she does surf and enjoy the beach. But in her free time you’ll find her riding horses or doing yoga along the Charles River.
