First Principles Calculation of Elastic Moduli of Early-Late Transition Metal Alloys
William Paul Huhn, Michael Widom, Andrew M. Cheung +3
Motivated by interest in the elastic properties of high strength amorphous metals, we examine the elastic properties of select crystalline phases. Using first principles methods, w…
Structural and magnetic properties of Cr-diluted CoFeB
Yishen Cui, Manli Ding, S. Joseph Poon +5
The crystallization process and the magnetization of Cr diluted CoFeB was investigated in both ribbon samples and thin film samples with Cr content up to 30 at. %. A primary crysta…
Significant ZT Enhancement in p-type Ti(Co,Fe)Sb-InSb Nanocomposites via a Synergistic High Mobility Electron Injection Energy filtering and Boundary Scattering Approach
Wenjie Xie, Yonggao Yana, Song Zhuc +8
It has been demonstrated that InSb nanoinclusions, which are formed in situ, can simultaneously improve all three individual thermoelectric properties of the n-type half Heusler co…
Perpendicular magnetization of Co20Fe50Ge30 films induced by MgO interface
Manli Ding, S. Joseph Poon
Epitaxial growth of Co20Fe50Ge30 thin film on single crystal MgO (001) substrate is reported. Structure characterization revealed (001)-oriented B2 order of CoFeGe well lattice mat…
Strain-induced enhancement of coercivity in amorphous TbFeCo films
Nattawut Anuniwat, Manli Ding, S. J. Poon +2
We report a strong size dependence of coercivity in amorphous ferrimagnetic TbFeCo films. The as-deposited film exhibited a low saturation magnetization (Ms=100 emu/cc) and a high…
Amorphous GdFeCo Films Exhibiting Large and Tunable Perpendicular Magnetic Anisotropy
Manli Ding, S. Joseph Poon
We report the compositional and temperature dependence of magnetic compensation in amorphous GdFeCo films. Magnetic compensation is attributed to the competition between antiferrom…
Thermal Conductivity of Core-Shell Based Nanocomposites for Enhancing Thermoelectric ZT
S. J. Poon, A. S. Petersen, Di Wu
The differential effective medium method (DEM) is presented from a physical viewpoint and employed to calculate the lattice thermal conductivity of nano-bulk composites comprising…
Effective Scattering Cross-section in Lattice Thermal Conductivity Calculation with Differential Effective Medium Method
Di Wu, A. S. Petersen, S. J. Poon
To further reduce the lattice thermal conductivity of thermoelectric materials, the technique of embedding nano-inclusions into bulk matrix materials, in addition to point defect s…
