Since the beginning of this month, I have been in Zürich for visiting the group of Prof. Pietro Gambardella at ETH Zürich, and I am going to stay until the end of the month. The main purpose of the visit is to have in-depth discussion on the orbital transport effects in magnetic heterostructues and interfaces. …
Visit of the Institute of PHysics of the Czech Acdemy of Science
In the previous week, I visitied the Institute of Physics of Czech Academy of Science, thanks to the invitation by Helena (Reichlova). She showed great interest since the last SPICE junior workshop in Ingelheim, but unfotunately I did not have chance to explain big ideas and basic aspects. My talk in that workshop was rather …

Back to normal working routine
I have been on a quite long vacation recently and had wonderful time. It was the first time since I started my PhD study that I haven't really studied or worked more than 2 months. Sure, I was thinking about physics and science, but my thoughts were more from very childish curiosity, like "how does …
“Inverse” orbital torque and “spin-to-orbital” conversion
Another recent experimental paper in which I got coauthored in 2023 is one from the group of Antonio Azevedo in Federal University of Pernambuco: E. Santos, J. E. Abrão, Dongwook Go, L. K. de Assis, Y. Mokrousov, J.B.S. Mendes, A. AzevedoInverse Orbital Torque via Spin-Orbital Interwined StatesPhysical Review Applied 19, 014069 (2023) *Editor’s Suggestion As far as I …

> 50 nm orbital relaxation length revealed
Some time ago, I submitted a theory paper that predicts exceptionally long orbital dephasing in ferromagnets: Dongwook Go, Daegeun Jo, Kyoung-Whan Kim, Soogil Lee, Min-Gu Kang, Byong-Guk Park, Stefan Blügel, Hyun-Woo Lee, Yuriy MokrousovLong-Range Orbital Magnetoelectric Torque in FerromagnetsarXiv:2106.07928 (Yes, it's still "Under Review" because the process took time, and I myself also took a …

A little side project that can be useful for junior-level reserachers
I have always thought, it would be nice to make a series notes of essential toolkits for everyone to know in the field of magnetism/spintronics. Sure, I am talking about theroetical tools -- I am quite ignorant of any experimental tools, even rudimentary ones like x-ray diffraction and Hall measurements. One of the main motivations …

Lots of things happened in 2022
I realized that I did not post any blog article since summer. I would like to tell everyone that I am well and not dead. But the year of 2022 was the busiest moment so far in my academic career. First, now that there is almost no Covid-related restrictions, I suddenly started to travel a …
Young Researcher’s Workshop
In this week, I participated in SPICE Young Research Leaders Group Workshop, which was organized by Alex and Helena. It was held in Ingelheim, a charming village located not so far from Mainz and famous for many wineries in the neighborhood. As the workshop title says, only junior-level researchers could join the workshop, and the …
DFT lectures
JGU Mainz campus In the last week, just before the Easter holidays, I visited Mainz for giving lectures on the density functional theory. It was an intensive course style, rather than a broad introduction over a semester, and I dealt with lots of practical aspects. I skipped all formal stuffs such as the Hohenberg-Kohm theorem …
Trip to Marseille
In the previous week, I visited a colleague of mine in Marseille. Although I have been to several workshops within Germany in recent years, I just realized that this was my first busienss trip to a foreign country since 2020, which excited me a bit. As I am trying to be more responsible for my …
