Atomic layer molecular beam epitaxy of kagome magnet RMn6Sn6 (R = Er, Tb) thin films

Autor: Shuyu Cheng, Binzhi Liu, Igor Lyalin, Wenyi Zhou, Jinwoo Hwang, Roland K. Kawakami

Publikováno v: APL Materials, Vol 12, Iss 4, Pp 041129-041129-7 (2024)

Kagome lattices have garnered substantial interest because their band structure consists of topological flat bands and Dirac cones. The RMn6Sn6 (R = rare earth) compounds are particularly interesting because of the existence of the large intrinsic an

Atomic layer epitaxy of kagome magnet Fe3Sn2 and Sn-modulated heterostructures

Autor: Shuyu Cheng, Binbin Wang, Igor Lyalin, Núria Bagués, Alexander J. Bishop, David W. McComb, Roland K. Kawakami

Publikováno v: APL Materials, Vol 10, Iss 6, Pp 061112-061112-7 (2022)

Magnetic materials with kagome crystal structure exhibit rich physics, such as frustrated magnetism, skyrmion formation, topological flat bands, and Dirac/Weyl points. Until recently, most studies on kagome magnets have been performed on bulk crystal

Spin–Orbit Torque in Bilayers of Kagome Ferromagnet Fe3Sn2 and Pt

Autor: Shuyu Cheng, Igor Lyalin, Roland Kawakami

Publikováno v: Nano Letters. 21:6975-6982

Spin-orbit torque phenomena enable efficient manipulation of the magnetization in ferromagnet/heavy metal bilayer systems for prospective magnetic memory and logic applications. Kagome magnets are of particular interest for spin-orbit torque due to t

Kinetically-controlled epitaxial growth of Fe$_3$GeTe$_2$ van der Waals ferromagnetic films

Autor: Wenyi Zhou, Alexander J. Bishop, Menglin Zhu, Igor Lyalin, Robert Walko, Jay A. Gupta, Jinwoo Hwang, Roland K. Kawakami

We demonstrate that kinetics play an important role in the epitaxial growth of Fe$_3$GeTe$_2$ (FGT) van der Waals (vdW) ferromagnetic films by molecular beam epitaxy. By varying the deposition rate, we control the formation or suppression of an initi
