Thermal Conductivity of BAs under Pressure
Songrui Hou, Bo Sun, Fei Tian +7
The thermal conductivity of boron arsenide (BAs) is believed to be influenced by phonon scattering selection rules due to its special phonon dispersion. Compression of BAs leads to…
Thermal expansion coefficient and lattice anharmonicity of cubic boron arsenide
Xi Chen, Chunhua Li, Fei Tian +6
Recent measurements of an unusual high thermal conductivity of around 1000 W m-1 K-1 at room temperature in cubic boron arsenide (BAs) confirm predictions from theory and suggest p…
Direct observation of magnon-phonon coupling in yttrium iron garnet
Haoran Man, Zhong Shi, Guangyong Xu +7
The magnetic insulator yttrium iron garnet (YIG) with a ferrimagnetic transition temperature of 560 K has been widely used in microwave and spintronic devices. Anomalous feat…
Effects of Grain Boundaries and Defects on Anisotropic Magnon Transport in Textured Sr14Cu24O41
Xi Chen, Karalee Jarvis, Sean Sullivan +3
The strong spin-spin exchange interaction in some low-dimensional magnetic materials can give rise to a high group velocity and thermal conductivity contribution from magnons. One…
Weak coupling of pseudoacoustic phonons and magnon dynamics in incommensurate spin ladder compound Sr14Cu24O41
Xi Chen, Dipanshu Bansal, Sean Sullivan +5
Intriguing lattice dynamics has been predicted for aperiodic crystals that contain incommensurate substructures. Here we report inelastic neutron scattering measurements of phonon…
