I released TopDock v0.1, a native macOS menu-bar utility that turns the MacBook notch—or the top-center of an external display—into a quick launcher for folders and apps. The panel can be opened by pushing the cursor into the hotspot, pressing ⌥Space, or using the menu-bar icon. It supports in-panel folder navigation, search, sorting, Quick Look, drag-and-drop file handling, multiple workspaces, and Korean/English interfaces. The Apple Silicon build for macOS 14 or later is available from the Project page.
I released Figure Creator v7, a desktop application for creating publication-ready scientific figures from measurement data. Version 7 supports 2D, polar, 3D, heatmap, surface, bar, and multi-panel figures, together with interactive layout editing, journal size presets, LaTeX labels, error bars, broken axes, and high-resolution export. The macOS build for Apple Silicon and English/Korean manuals are available from the Project page.
I received the STAR Outstanding Graduate Student Award from the Korean Magnetics Society (KMS) 2026.
I received the Excellent Student Researcher Award from KIST (Post-Silicon Semiconductor Institute), 2025.
I delivered an invited talk at the 70th Annual 2025 MMM Conference held in West Palm Beach, Florida. My presentation, titled "Self-generated Spin–orbit Torques Driven by Magnonic Spin Dissipation in Antiferromagnet/Ferromagnet Bilayers," introduced our recent findings on magnon-mediated spin–orbit torque mechanisms and their implications for spintronic device applications.
I am honored to have received the Condensed Matter Physics MSM Award at the 2025 Fall Meeting of the Korean Physical Society. This recognition encourages me to continue pursuing meaningful research in spintronics and condensed matter physics.
I developed a sequential magnetization switching program using the Keithley 6221 and 2182A. To verify pulse-induced deterministic switching, applying sequential pulse currents with alternating polarity and measuring the anomalous Hall resistance is an effective approach. With this program, I can control the amplitude, width, and interval of the pulses. Additionally, I can configure the sequence by specifying the positive or negative polarity and preview the pulse patterns before starting a measurement.
I attended the 2025 Summer Korean Magnetics Society (KMS) Conference held on Jeju Island from June 3 to June 5, 2025. During the conference, I presented a poster titled "Magnonic Spin Dissipation Driven Anisotropic Spin Torque in Easy-Axis Antiferromagnet/Ferromagnet Bilayer."
Claude's MCP function has many amazing features. Previously, I installed web crawling functionality in Claude using MCP and confirmed that it works very effectively. This time, I've added a feature that allows us to check the extensibility with other programs, which can be considered the core of MCP, not just simple web crawling functionality. When the Blender MCP function is installed, Claude can directly access Blender and model in real-time according to my commands. The above result was produced with the command "Model a person being chased by a monster in a house with a pretty yard." The image on the right is the result of a simple command "Model the structure of Graphene." It's truly amazing.
I created a new I–V curve measurement program using Python. Although it could have been easily written with LabVIEW, the purpose of this project was to completely write a measurement program using Python and AI, as LabVIEW, being a GUI language, is not easy to utilize with AI. The program's function is not to measure DC current I–V curves, but to apply desired AC currents and collect the corresponding 1st & 2nd harmonic signals. I wrote it to perform forward & backward sweeps within the set current range and to allow setting the desired frequency. AI isn't yet able to write a perfect program all at once, but I think there's significance in it helping to establish the framework for parts that were quite cumbersome and inconvenient. After modifying a few minor aspects, I was able to obtain a program that works very successfully.
Having heard the news about the Model Context Protocol (MCP) feature update for Claude, I decided to try creating a system to search for academic papers through Claude using this functionality. I've set up the Firecrawl MCP feature with Claude and written a prompt that allows me to explore papers in my desired field/journal and organize them into HTML slides. It seems to be working well, but it takes slightly long.
