Magnetization controlled by crystallization in soft magnetic Fe-Si-B-P-Cu alloys
Hiroshi Nakajima, Akihiro Osako, Noriharu Yodoshi +8
Soft magnetic materials have low coercive fields and high permeability. Recently, nanocrystalline alloys obtained using annealing amorphous alloys have attracted much interest sinc…
Giant Negative Thermal Expansion Induced by the Synergistic Effects of Ferroelectrostriction and Spin-Crossover in PbTiO3-Based Perovskites
Zhao Pan, Jun Chen, Runze Yu +18
The discovery of unusual negative thermal expansion (NTE) provides the opportunity to control the common but much desired property of thermal expansion, which is valuable not only…
Magnetism in amorphous carbon
Yuki Sakai, James R. Chelikowsky, Marvin L. Cohen
We investigate magnetism in amorphous carbon as suggested by the recently reported ferromagnetism in a new form of amorphous carbon. We use spin constrained first-principles simula…
Effect of Lead Substitution on LaO0.5F0.5BiS2
S. Otsuki, S. Demura, Y. Sakai +2
We examined Lead (Pb) Substitution effect on a single crystal of a layered superconductor LaO0.5F0.5BiS2. Pb concentration dependence of the lattice constant showed slight anomaly…
Structural stability and energy-gap modulation through atomic protrusion in freestanding bilayer silicene
Yuki Sakai, Atsushi Oshiyama
We report on first-principles total-energy and phonon calculations that clarify structural stability and electronic properties of freestanding bilayer silicene. By extensive struct…
Effect of Sn-substitution on Thermoelectric Properties of Copper-based Sulfide, Famatinite Cu3SbS4
Yosuke Goto, Yuki Sakai, Yoichi Kamihara +1
Copper-based sulfide is an attractive material for Earth-abundant thermoelectrics. In this study, we demonstrate the effect of Sn-substitution on the electrical and thermal transpo…
