Boundary scattering in micro-size crystal of topological Kondo insulator SmB
Narayan Poudel, Daniel J. Murray, Jason R. Jeffries +1
We have studied the effects of phonon-boundary scattering on the thermal transport in topological Kondo insulator, SmB. The studies have been performed by using the method…
Advances in actinide thin films: synthesis, properties, and future directions
K. D. Vallejo, F. Kabir, N. Poudel +5
Actinide-based compounds exhibit unique physics due to the presence of 5f electrons, and serve in many cases as important technological materials. Targeted thin film synthesis of a…
Capturing the ground state of uranium dioxide from first principles: crystal distortion, magnetic structure, and phonons
Shuxiang Zhou, Hao Ma, Enda Xiao +5
Uranium dioxide (UO) remains a formidable challenge for first-principles approaches, due to the complex interplay among spin-orbit coupling, Mott physics, magnetic ordering, an…
High Phonon Scattering Rates Suppress Thermal Conductivity in Hyperstoichiometric Uranium Dioxide
Hao Ma, Matthew S. Bryan, Judy W. L. Pang +4
Uranium dioxide (UO), one of the most important nuclear fuels, can accumulate excess oxygen atoms as interstitial defects, which significantly impacts thermal properties. In th…
Magnetoelastic standing waves induced in UO by microsecond magnetic field pulses
Rico Schönemann, George Rodriguez, Dwight Rickel +9
Magnetoelastic measurements in the piezomagnetic antiferromagnet UO were performed via the fiber Bragg grating method in magnetic fields up to generated by…
Reentrant spin reorientation transition and Griffiths-like phase in antiferromagnetic TbFeCrO
Bhawana Mali, Harikrishnan S. Nair, T. W. Heitmann +6
The perovskite TbFeCrO shows two anomalies in the magnetic susceptibility at = 257K and = 190K which are respectively, the antiferromagnetic and…
The grain-size effect on thermal conductivity of uranium dioxide
K. Shrestha, T. Yao, J. Lian +4
We have investigated the grain boundary scattering effect on the thermal transport behavior of uranium dioxide (UO). The polycrystalline samples having different grain-sizes (0…
Magnetic and transport properties of rare-earth-based half-Heusler phases RPdBi: prospective systems for topological quantum phenomena
K. Gofryk, D. Kaczorowski, T. Plackowski +2
RPdBi (R = Er, Ho, Gd, Dy, Y, Nd) compounds were studied by means of x-ray diffraction, magnetic susceptibility, electrical resistivity, magnetoresistivity, thermoelectric power an…
