Publikováno v: Journal of Science: Advanced Materials and Devices, Vol 9, Iss 1, Pp 100649- (2024)

Recently, vast research has been under investigation on the role of chirality in magnetization dynamics, an area that currently lacks a comprehensive understanding. To gain further insight into the importance of chirality, we explore the effects of v

Improved spin–orbit torque induced magnetization switching efficiency by helium ion irradiation

Autor: Suhyeok An, Eunchong Baek, Jin-A Kim, Ki-Seung Lee, Chun-Yeol You

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-10 (2022)

Abstract Increasing the efficiency of spin–orbit torque (SOT) is of great interest in spintronics devices because of its application to the non-volatile magnetic random access memory and in-logic memory devices. Accordingly, there are several studi

Confidence-aware Denoised Fine-tuning of Off-the-shelf Models for Certified Robustness

Autor: Jang, Suhyeok, Kim, Seojin, Shin, Jinwoo, Jeong, Jongheon

The remarkable advances in deep learning have led to the emergence of many off-the-shelf classifiers, e.g., large pre-trained models. However, since they are typically trained on clean data, they remain vulnerable to adversarial attacks. Despite this

Role of the chiral spin configuration in field-free spin-orbit torque-induced magnetization switching by a locally injected spin current

Autor: An, Suhyeok, Seo, Hyeong-Joo, Baek, Eunchong, Lee, Soobeom, You, Chun-Yeol

For deterministic magnetization switching by spin-orbit torque (SOT) in a perpendicular magnetic anisotropy system, an additional in-plane direction magnetic field is essential for deterministic switching by breaking the magnetization symmetry. Reali
