Ising-Type Magnetic Ordering in Atomically Thin FePS3.
Jae-Ung Lee,Sungmin Lee,Ji Hoon Ryoo,Soonmin Kang,Tae Yun Kim,Pilkwang Kim,Cheol-Hwan Park,Je-Geun Park,Hyeonsik Cheong +8 more
TL;DR: It is demonstrated that FePS3 exhibits an Ising-type antiferromagnetic ordering down to the monolayer limit, in good agreement with the Onsager solution for two-dimensional order-disorder transition.

Suppression of magnetic ordering in XXZ-type antiferromagnetic monolayer NiPS 3
Kangwon Kim,Soo Yeon Lim,Jae-Ung Lee,Sungmin Lee,Tae Yun Kim,Kisoo Park,Gun Sang Jeon,Cheol-Hwan Park,Je-Geun Park,Hyeonsik Cheong +9 more
TL;DR: In this paper, it was shown that the XXZ-type antiferromagnetic order of a magnetic van der Waals material, NiPS3, behaves upon reducing the thickness and ultimately becomes unstable in the monolayer limit.

Coherent many-body exciton in van der Waals antiferromagnet NiPS3.
Soonmin Kang,Kangwon Kim,Beom Hyun Kim,Jonghyeon Kim,Kyung Ik Sim,Jae-Ung Lee,Jae-Ung Lee,Sungmin Lee,Kisoo Park,Seokhwan Yun,Taehun Kim,Abhishek Nag,A. C. Walters,M. Garcia-Fernandez,Jiemin Li,Laurent Chapon,Ke-Jin Zhou,Young-Woo Son,Jae Hoon Kim,Hyeonsik Cheong,Je-Geun Park +20 more
TL;DR: It is shown that a spin–orbit-entangled exciton state appears below the Néel temperature of 150 kelvin in NiPS3, an antiferromagnetic van der Waals material, and is found to arise from many-body states of a Zhang–Rice singlet.

Charge-Spin Correlation in van der Waals Antiferromagnet NiPS 3
So Yeun Kim,Tae Yun Kim,Luke J. Sandilands,Soobin Sinn,Min-Cheol Lee,Jaeseok Son,Sungmin Lee,Kiyoung Choi,Wondong Kim,Byeong-Gyu Park,Cheolho Jeon,Hyeong-Do Kim,Cheol-Hwan Park,Je-Geun Park,S. J. Moon,Tae-Hee Noh +15 more
TL;DR: This work demonstrates that layered transition-metal trichalcogenide magnets are useful candidates for the study of correlated-electron physics in two-dimensional magnetic materials.

TL;DR: In this article, high-pressure neutron studies of so-called magnetic graphene reveal exotic new states and behaviors as the material transitions from an insulator to a metal when compressed with high pressure.
