Magnetization processes and spin dynamics across field-induced phase transitions in the quasi-two-dimensional quantum magnet Cu(OH)Br

Anneke Reinold, Dirk Wulferding, Laur Peedu +13

We present magnetic-field-dependent evolution of magnetization and spin dynamics in the quasi-two-dimensional spin- magnet , consisting of alternately c…

Raman Circular Dichroism Reveals Higher-Order Quantum Geometry of Magnons

Yong Chan Kim, Youngsu Choi, Kwang-Yong Choi +1

We develop a gauge-invariant framework that relates two-magnon Raman circular dichroism (RCD) to higher-order magnon quantum geometry. In the magnon band basis, the Raman operator…

Plaid-Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe

Dirk Wulferding, Daehyeon An, Jiwon Choi +8

Altermagnets constitute an emerging class of magnetic materials that combine compensated antiferromagnetic order with spin-split excitations arising from crystalline symmetries. De…

Spinon excitations and spin correlations in the one-dimensional quantum magnet -VOSO probed by Raman spectroscopy

Dirk Wulferding, Diana Lucia Quintero-Castro, Pontus Laurell +3

Fractionalized excitations such as spinons and anyons have emerged as a central theme in condensed matter physics with broad implications for superconductivity, quantum statistics,…

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…

Magnetism and spin dynamics of an S=3/2 frustrated trillium lattice antiferromagnet K2CrTi(PO4)3

J. Khatua, Suheon Lee, Gyungbin Ban +3

Competing magnetic interactions, frustration driven quantum fluctuations, and spin correlations offer an ideal route for the experimental realization of emergent quantum phenomena…
