Anti-sites disordering suppression of the possible phase transition in Mn2CrGa
H. G. Zhang, J. Chen, E. K. Liu +4
Theoretical and experimental characterizations of Mn2CrGa compound in regard to the possibility of phase transformation have been carried out in this work. Under a high ordering L2…
New spin injection scheme based on spin gapless semiconductors: A first-principles study
G. Z. Xu, X. M. Zhang, Z. P. Hou +8
Spin injection efficiency based on conventional and/or half-metallic ferromagnet/semiconductor is greatly limited by the Schmidt obstacle due to conductivity mismatch, here we prop…
Structural and magnetic properties of MnCo1-xFexSi alloys
J. H. Chen, Z. Y. Wei, E. K. Liu +3
The crystal structures, martensitic structural transitions and magnetic properties of MnCo1-xFexSi (0 <= x <= 0.50) alloys were studied by differential scanning calorimetry (DSC),…
Microscopic dynamics perspective on the relationship between Poisson ratio and ductility of metallic glasses
K. L. Ngai, Li-Min Wang, Riping Liu +1
In metallic glasses a clear correlation had been established between plasticity or ductility with the Poisson ratio and alternatively the ratio of the elastic bulk modulus to the s…
A new class of topological insulators from I-III-IV half-Heusler compounds with strong band inversion strength
X. M. Zhang, G. Z. Xu, Y. Du +4
In this paper, by first principle calculations, we investigate systematically the band topology of a new half-Heusler family with composition of I(A)-III(A)-IV(A). The results clea…
