Collapse of Jahn-Teller Phonons in LaSrMnO with Weak Magnetoresistance
Tyler C. Sterling, Andrei T. Savici, Ryoichi Kajimoto +4
Perovskite manganites are quantum materials exhibiting competing interactions inducing colossal magnetoresistance (CMR). The prevailing theory of CMR highlights the essential role…
Magnetic Signature of Chiral Phonons Revealed by Neutron Spectroscopy in Ferrimagnetic FeZnMoO
Song Bao, Junbo Liao, Zhentao Huang +13
Lattice vibrations can carry angular momentum and magnetic moments under broken inversion or time-reversal symmetry, forming so-called chiral phonons. While such excitations have b…
Refined spin Hamiltonian on the Cairo pentagonal lattice of Bi2Fe4O9
Emma Y. Lenander, Frida B. Nielsen, Jakob Lass +14
The frustrated magnet Bi2Fe4O9 has been reported to exhibit complex spin dynamics coexisting with conventional spin wave excitations. The magnetic Fe3+ (S = 5/2) ions are arranged…
From weakly interacting spinons to tightly bound triplons in the frustrated quantum spin-Peierls chain
Pyeongjae Park, Bo Xiao, Karolina Górnicka +7
Fractionalized quasiparticles and their confinement into emergent bound states lie at the heart of modern quantum magnetism. While the evolution into magnonic bound states has been…
Phonon spectrum in the spin-Peierls phase of CuGeO
L. Spitz, A. Razpopov, S. Biswas +10
CuGeO has long been studied as a prototypical example of the spin-Peierls transition in a Heisenberg chain. Despite intensive investigation of this quasi-one-dimensio…
Universal whirling magnetic orders in non-Heisenberg Tsai-type quasicrystal approximants
Farid Labib, Kazuhiro Nawa, Yusuke Nambu +9
Magnetic orders of non-Heisenberg Tsai-type 1/1 approximant crystals (ACs) in the Au-Ga-Dy system were studied through bulk magnetization, neutron diffraction, and inelastic neutro…
