Spin Seebeck effect and magnon diffusion length in $Fe_{3} O_{4}$

G. Venkat, C. D. W. Cox, D. Voneshen +4

The determination of the magnon diffusion length (MDL) is important for increasing the efficiency of spin Seebeck effect (SSE) based devices utilising non-metallic magnets. We extr…

Anomalous Dispersion of LO Phonons in Oxygen-Doped La $_{2 - x}$ Sr $_{x}$ CuO $_{4 + δ}$

Tim Tejsner, Andrea Piovano, Ana Ţuţueanu +5

Inelastic neutron scattering has been used to study the in-plane Cu-O bond-stretching mode in oxygen doped La $_{1.94}$ Sr $_{0.06}$ CuO $_{4.035}$ ( $T_{c} = 38 K$ ) and La $_{2}$ CuO$…

Magnetic structure and excitations of the topological semimetal YbMnBi $_{2}$

Jian-Rui Soh, Henrik Jacobsen, Bachir Ouladdiaf +9

We investigated the magnetic structure and dynamics of YbMnBi $_{2}$ , with elastic and inelastic neutron scattering, to shed light on the topological nature of the charge carriers in…

Lattice dynamics coupled to charge and spin degrees of freedom in the molecular dimer-Mott insulator $κ$ -(BEDT-TTF) $_{2}$ Cu[N(CN) $_{2}$ ]Cl

Masato Matsuura, Takahiko Sasaki, Satoshi Iguchi +11

Inelastic neutron scattering measurements on the molecular dimer-Mott insulator $κ$ -(BEDT-TTF) $_{2}$ Cu[N(CN) $_{2}$ ]Cl reveal a phonon anomaly in a wide temperature range. Starting…

Antiferromagnetic correlations in the metallic strongly correlated transition metal oxide LaNiO $_{3}$

H. Guo, Z. W. Li, L. Zhao +10

The material class of rare earth nickelates with high Ni $^{3 +}$ oxidation state is generating continued interest due to the occurrence of a metal-insulator transition with charge o…

Incommensurate spin correlations in highly oxidized cobaltates La $_{2 - x}$ Sr $_{x}$ CoO $_{4}$

Z. W. Li, Y. Drees, C. Y. Kuo +13

We observe quasi-static incommensurate magnetic peaks in neutron scattering experiments on layered cobalt oxides La2-xSrxCoO4 with high Co oxidation states that have been reported…
