Highly fluctuating double- magnetic order in the van der Waals metal CeTe

Ryutaro Okuma, Yuita Fujisawa, Natsumi Maekawa +5

CeTe is a van der Waals antiferromagnet composed of magnetic [CeTe] layers coupled to highly conducting Te square nets. Its simple quasi-two-dimensional electronic…

Dimensional reduction by geometrical frustration in a cubic antiferromagnet composed of tetrahedral clusters

Ryutaro Okuma, Maiko Kofu, Shinichiro Asai +10

Dimensionality is a critical factor in determining the properties of solids and is an apparent built-in character of the crystal structure. However, it can be an emergent and tunab…
