Autor: Lee, Jae Hyuck, Kim, GwanWoo, Song, Inkyung, Kim, Yejin, Lee, Yeonjae, Yoo, Sung Jong, Cho, Deok-Yong, Rhim, Jun-Won, Jung, Jongkeun, Kim, Gunn, Kim, Changyoung

In condensed matter physics, the Kagome lattice and its inherent flat bands have attracted considerable attention for their potential to host a variety of exotic physical phenomena. Despite extensive efforts to fabricate thin films of Kagome material

Linear scaling relationship of N\'{e}el temperature and dominant magnons in pyrochlore ruthenates

Autor: Lee, Jae Hyuck, Wulferding, Dirk, Kim, Junkyoung, Song, Dongjoon, Park, Seung Ryong, Kim, Changyoung

Publikováno v: Phys. Rev. B 108, 054443 (2023)

We present a systematic Raman spectroscopy study on a series of pyrochlore ruthenates, a system which is not yet clearly settled on its magnetic origin and structure. Apart from the Raman-active phonon modes, new peaks that appear in the energy range

The emergence of scalar Higgs-type amplitude modes in systems where symmetry is spontaneously broken has been a highly successful, paradigmatic description of phase transitions, with implications ranging from high-energy particle physics to low-energ
