Tunnel magnetoresistance effect with a Cr-doped altermagnet
Katsuhiro Tanaka, Takuya Nomoto, Ryotaro Arita
Antiferromagnets can have a finite spin-polarization in the momentum space when their magnetic structure breaks the macroscopic time-reversal symmetry. This spin-polarization can p…
Systematic Magnetic Structure Generation Based on Oriented Spin Space Groups: Formulation, Applications, and High-Throughput First-Principles Calculations
Takuya Nomoto, Kohei Shinohara, Hikaru Watanabe +1
We propose a framework for generating magnetic structures, inspired by the concept of oriented spin space groups (SSGs): magnetic structures are first generated as totally symmetri…
Entropy-assisted, long-period stacking of honeycomb layers in an AlB2-type silicide
Leonie Spitz, Takuya Nomoto, Shunsuke Kitou +8
Configurational entropy can impact crystallization processes, tipping the scales between structures of nearly equal internal energy. Using alloyed single crystals of Gd2PdSi3 in th…
Spin Models and Cluster Multipole Method: Application to Kagome Magnets
Juba Bouaziz, Takuya Nomoto, Ryotaro Arita
We present a multi-scale computational approach that combines atomistic spin models with the cluster multipole (CMP) method. The CMP method enables a systematic and accurate genera…
Symmetry-adapted closest Wannier modeling based on complete multipole basis set
Rikuto Oiwa, Akane Inda, Satoru Hayami +3
We have developed a method to construct a symmetry-adapted Wannier tight-binding model based on the closest Wannier formalism and the symmetry-adapted multipole theory. Since the s…
Nernst effect of high-mobility Weyl electrons in NdAlSi enhanced by a Fermi surface nesting instability
Rinsuke Yamada, Takuya Nomoto, Atsushi Miyake +7
The thermoelectric Nernst effect of solids converts heat flow to beneficial electronic voltages. Here, using a correlated topological semimetal with high carrier mobility in pr…
