Emergent zero-field anomalous Hall effect in a reconstructedrutileantiferromagnetic metal
Meng Wang, Katsuhiro Tanaka, Shiro Sakai +11
Anomalous Hall effect (AHE) emerged in antiferromagnetic metals shows intriguing physics and application potential. In contrast to certain noncollinear antiferromagnets, rutile RuO…
Local density of states as a probe for tunneling magnetoresistance effect: application to ferrimagnetic tunnel junctions
Katsuhiro Tanaka, Takuya Nomoto, Ryotaro Arita
We investigate the tunneling magnetoresistance (TMR) effect using the lattice models which describe the magnetic tunnel junctions (MTJ). First, taking a conventional ferromagnetic…
Finite temperature thermodynamic properties of the spin-1 nematics in an applied magnetic field
Katsuhiro Tanaka, Chisa Hotta
We study numerically the thermodynamic properties of the spin nematic phases in a magnetic field in the spin-1 bilinear-biquadratic model. When the field is applied, the phase tran…
Abundant quadrupolar or nematic phases driven by the Heisenberg interactions in a spin-1 dimer system forming a bilayer
Katsuhiro Tanaka, Chisa Hotta
We explore several classes of quadrupolar ordering in a system of antiferromagnetically coupled quantum spin-1 dimers, which are stacked in the triangular lattice geometry forming…
Origin of Biquadratic Exchange Interactions in a Mott Insulator as a Driving Force of Spin Nematic Order
Katsuhiro Tanaka, Yuto Yokoyama, Chisa Hotta
We consider a series of Mott insulators in unit of two orbitals each hosting spin-1/2 electron, and by pairing two spin-1/2 into spin-1 triplet, derive the effective exchange inter…
