Magnetic properties of a quasi-two-dimensional spin-1/2 antiferromagnet Y2CuGe4O12
J. Khatua, Changhyun Koo, Suyoung Kim +7
Competing magnetic interactions and frustration-induced quantum fluctuations in spatially anisotropic low-dimensional magnets often give rise to exotic magnetic phenomena, includin…

Coexistence of anomalous spin dynamics and weak magnetic order in a chiral trillium lattice K2FeSn(PO4)3
J. Khatua, S. Krishnamoorthi, Changhyun Koo +13
Trillium lattices, where magnetic ions form a three-dimensional chiral network of corner-sharing equilateral triangular motifs, offer a prominent platform to explore exotic quantum…

Two-stage evolution of magnetic correlations in spiral spin liquid material, CaCrO
Changhyun Koo, Jaena Park, Johannes Werner +7
We present an X-band and tunable high-frequency/high-field electron spin resonance (HF-ESR) study of single-crystalline CaCrO, which constitutes alternating ant…
