Electric Current Control of Helimagnetic Chirality from a Multidomain State in the Helimagnet MnAu
Yuta Kimoto, Hidetoshi Masuda, Jun-ichiro Ohe +3
In this paper, we study the domain wall dynamics under electric current in the helimagnet MnAu. We have found that the threshold electric current of the transition from a multi…
Current-induced sliding motion in a helimagnet MnAu
Yuta Kimoto, Hidetoshi Masuda, Takeshi Seki +4
We found signatures of current-induced sliding motion in helimagnetic thin films. An abrupt change in differential resistivity occurred at a threshold bi…
Current-induced shuttlecock-like movement of non-axisymmetric chiral skyrmions
Remi Murooka, Andrey O. Leonov, Katsuya Inoue +1
Current-induced motion of non-axisymmetric skyrmions within angular phases of polar helimagnetis with the easy plane anisotropy is studied by micromagnetic simulations.Such non-axi…
Conversion of Heat into Charge Current by the Spin Wave Anomalous Nernst Effect
M. Mizuguchi, K. Hasegawa, J. Ohe +3
A novel process of spin conversion from a temperature gradient to a transverse voltage is addressed in this paper, viz. the anomalous Nernst effect (ANE) in a ferromagnetic metal.…
Spin Seebeck insulator
K. Uchida, J. Xiao, H. Adachi +10
Thermoelectric generation is an essential function of future energy-saving technologies. However, this generation has been an exclusive feature of electric conductors, a situation…
Combined approach of density functional theory and quantum Monte Carlo method to electron correlation in dilute magnetic semiconductors
Jun-ichiro Ohe, Yoshihiro Tomoda, Nejat Bulut +3
We present a realistic study for electronic and magnetic properties in dilute magnetic semiconductor (Ga,Mn)As. A multi-orbital Haldane-Anderson model parameterized by density-func…
