Tailoring the chirality of magnetic domain walls by interface engineering.
Gong Chen,Tianping Ma,Alpha T. N'Diaye,Hee Young Kwon,Changyeon Won,Yizheng Wu,Andreas K. Schmid +6 more
TL;DR: It is shown that the Dzyaloshinskii-Moriya interaction can be adjusted to stabilize either left-handed or right-handed Néel walls, or non-chiral Bloch walls by adjusting an interfacial spacer layer between the multilayers and the substrate.
Novel chiral magnetic domain wall structure in Fe/Ni/Cu(001) films.
Gong Chen,Gong Chen,Jiangbo Zhu,A. Quesada,J. Li,Alpha T. N'Diaye,Y. Huo,Tianping Ma,Yongzhu Chen,Hee Young Kwon,Changyeon Won,Ziqiang Qiu,Andreas K. Schmid,Yizheng Wu +13 more
TL;DR: Using spin-polarized low energy electron microscopy, a new type of domain wall structure is discovered in perpendicularly magnetized Fe/Ni bilayers grown epitaxially on Cu(100) suggesting that the underlying mechanism is the Dzyaloshinskii-Moriya interaction at the film interfaces.
Exchange Bias in Weakly Interlayer-Coupled van der Waals Magnet Fe3GeTe2.
Hyung Keun Gweon,Sangyeop Lee,Hee Young Kwon,Juyoung Jeong,Hye Jung Chang,Hye Jung Chang,Kyoung-Whan Kim,Ziqiang Qiu,Hyejin Ryu,Chaun Jang,Jun Woo Choi +10 more
TL;DR: In this paper, the exchange bias effect is observed in the naturally oxidized vdW ferromagnet Fe3GeTe2, owing to an antiferromagnetic ordering in the surface oxide layer, and the magnitude and thickness dependence of the effect is unlike those expected in typical thin-film systems.

Apoptosis induction of Persicae Semen extract in human promyelocytic leukemia (HL-60) cells.
TL;DR: The antiproliferative effects of Persicae Semen extract appear to be attributable to its induction of apoptotic cell death, as Persicai Semen Extract induced nuclear morphology changes and intemucleosomal DNA fragmentation.

Inhibition of Wnt/β-catenin signaling mediates ursolic acid-induced apoptosis in PC-3 prostate cancer cells
Ji-Hyuk Park,Hee Young Kwon,Eun Jung Sohn,Kyung A. Kim,Bonglee Kim,Soo-Jin Jeong,Junho Song,Jin Suk Koo,Sung-Hoon Kim +8 more
TL;DR: The findings suggest that ursolic acid induces apoptosis via inhibition of the Wnt5/β-catenin pathway and activation of caspase in PC-3 prostate cancer cells, and support scientific evidence that medicinal plants containing ursoli acid can be applied to cancer prevention and treatment as a complement and alternative medicine (CAM) agent.
