Journal ArticleDOI
An End‐On Azide‐Bridged Antiferromagnetic Single‐Chain Magnet Involving Spin Canting and Field‐Induced Two‐Step Magnetic Transitions
TL;DR: The spin-canted phenomenon in the antiferromagnetic chain complex plays a pivotal role in establishing the slow magnetic relaxation.
Journal ArticleDOI
One‐Dimensional End‐To‐End Azide‐Bridged MnIII Complexes Incorporating Alkali Metal Ions: Slow Magnetic Relaxations and Metamagnetism
Jung Hee Yoon,Jin Wuk Lee,Dae Won Ryu,Sungwon Yoon,Byoung Jin Suh,Hyoung Chan Kim,Chang Seop Hong +6 more
TL;DR: In this system, spin canting definitely plays a central role in giving rise to the apparent slow magnetic relaxations in 1 and 2 because application of a high external magnetic field tends to destroy single-chain magnet (SCM) properties.
Journal ArticleDOI
Putative spin liquid in the triangle-based iridate Ba3IrTi2O9
Wonjun Lee,Seung-Hwan Do,Sungwon Yoon,Suheon Lee,Y. S. Choi,Dong-Jin Jang,Manuel Brando,Minseong Lee,Eun Sang Choi,Sungdae Ji,Z. H. Jang,B. J. Suh,K.-Y. Choi +12 more
TL;DR: In this paper, thermodynamic, magnetization, and muon spin relaxation measurements of the strong spin-orbit coupled iridate were reported, which constitutes a distinct frustration motif made up of a mixture of edge-and corner-sharing triangles.
Journal ArticleDOI
Cyanide-bridged WVMnIII single-chain magnet with isolated MnIII moieties exhibiting two types of relaxation dynamics
Jung Hee Yoon,Jin Wuk Lee,Dae Won Ryu,Sang Yup Choi,Sungwon Yoon,Byoung Jin Suh,Eui Kwan Koh,Hyoung Chan Kim,Chang Seop Hong +8 more
TL;DR: It is demonstrated that two types of relaxation processes are involved in the system; the low-T dynamics may come from magnetic domain dynamics and the high-T relaxation stems from the anionic chain, revealing single-chain magnet character.
Journal ArticleDOI
End-to-end azide-bridged manganese(III) chain compounds: field-induced magnetic phase transitions and variation of T(C) to 38 K depending on the side groups of the Schiff bases.
Jung Hee Yoon,Woo Ram Lee,Dae Won Ryu,Jin Wuk Lee,Sungwon Yoon,Byoung Jin Suh,Hyoung Chan Kim,Chang Seop Hong +7 more
TL;DR: Three one-dimensional coordination polymers bridged by end-to-end azides exhibit a field-induced metamagnetic transition from an antiferromagnetic state to a weak ferromagnetic phase, whereas 2 embraces aField-induced two-step magnetic phase transition.
