Quantum fluctuations associated with first-order magnetic transition in a frustrated kagome lattice antiferromagnet
Zhongchen Xu, Xinyang Liu, Cuiwei Zhang +7
Intense quantum fluctuations arising from geometrical frustrations in kagome-lattice magnets provide a feasible approach to exotic quantum states. Here, we document an unexpected i…

YbNiMg: Superheavy fermion with enhanced Wilson ratio and magnetocaloric effect
Xiaoci Zhang, Te Zhang, Zhaotong Zhuang +6
A comprehensive study of the low-temperature properties of YbNiMg has revealed evidence of a superheavy-fermion state, characterized by a large electronic specific-heat coeffic…
