Finally, covid has come to me. I started to cough and have headache. For a few days in the beginnin, all the self-tests that I performed were negative, but I was quite certain that this is covid because it has been around since a few weeks ago, at the workplace and accoreding to the contact-tracing …
Vacation in Ireland
In the last weekend, I visited Ireland for a short vacation as covid restrictions were mostly lifted. I had great time there. To be honest, I didn't know much about the country. Thanks to the trip, I had a chance to learn the people, their land, and their culture. At the end, I fell in …
Why I like giving seminar talks in small groups
In 2022, so far I have given three group seminars, roughly one per month. I think all of them went quite nice, not only for delivering the knowledge but also for exchanging ideas. What I like in particular was "friendly atmosphere" in which everyone asks questions and shares opinions freely (Probably it's because they are …

I still enjoy dirty works in science
Nowadays I spend more time in supervising someone than in my own project, and I am also involved in many other collaboration projects. A good thing is that as I discuss on various topics in spin-orbitronics, this really helps me to have a broader and comprehensive perspective on the field. However, I cannot spend too …
Recording a conference presentation
In the last week, I recorded my presentation for the upcoming Joint MMM-Intermag conference. I was invited to give a talk in the symposium Frontiers of Orbital Physics: Statics, Dynamics, and Transport of Orbital Angular Momentum, and my presentation is supposed to cover theoretical aspects of the orbital current, which is my main research expertise. …
Two more experimental papers on the orbital torque
This month, two experimental papers, in which I also contributed, have been published: Soogil Lee, Min-Gu Kang, Dongwook Go, Dohyoung Kim, Jun-Ho Kang, Taekhyeon Lee, Geun-Hee Lee, Nyun Jong Lee, Sanghoon Kim, Kab-Jin Kim, Kyung-Jin Lee, Byong-Guk ParkEfficient conversion of orbital Hall current to spin current for spin-orbit torque switchingCommunications Physics 4,234 (2021) Dongjoon Lee, Dongwook Go, Hyeon-Jong …

Orbitronics review paper
Continuing from the previous post, I recently wrote a perspective article on orbitronics, which can be found in this link. So far, there hasn't been much update and I confirmed that this article contains most of the up-to-date summary of the current understanding of the field. It's just a 7-page mini-review, so just take 20-30 …
Writing papers on orbitronics
It's hard to deny that orbitronics research is gaining more and more momentum and it became one of the fast-evolving fields in condensed matter physics, thanks to interests from neighboring areas such as spintronics, magnetism, 2D materials, and electron transport. I'm quite happy about the current status, especially after many years of working on this …
What I learned from advising other people
Since the last year, I started to advise a postdoc and PhD student who work on topics of my expertise. In our group, it's quite often that there are one or two more experienced researchers involved in advising together with direct supervisors who are usually professors. I find this system quite nice becaues one needs …

Spin-orbit torques in low-symmetry materials
Last Friday, I joined a seminar by Cheng Song on OSSS. While most of the time I just watch recorded talks from the OSSS because the usual schedule is from 3 pm ET, which is 9 pm CET and a bit late for me (especially for Friday evenings). But this time, since the speaker was …
