Inplane anisotropy of longitudinal thermal conductivities and weak localization of magnons in a disordered spiral magnet
Naoya Arakawa, Jun-ichiro Ohe
We demonstrate the inplane anisotropy of longitudinal thermal conductivities and the weak localization of magnons in a disordered screw-type spiral magnet on a square lattice. We c…
Negative magneto-thermal-resistance in a disordered two-dimensional antiferromagnet
Naoya Arakawa, Jun-ichiro Ohe
We demonstrate that a weak external magnetic field can induce negative magneto-thermal-resistance for magnons in a disordered two-dimensional antiferromagnet. We study the main eff…
Weak localization of magnons in a disordered two-dimensional antiferromagnet
Naoya Arakawa, Jun-ichiro Ohe
We propose the weak localization of magnons in a disordered two-dimensional antiferromagnet. We derive the longitudinal thermal conductivity for magnons of a disordered He…
Magnon Dispersion and Specific Heat of Chiral Magnets on the Pyrochlore Lattice
Naoya Arakawa
Chiral magnets are magnetically ordered insulators having spin scalar chirality, and magnons of chiral magnets have been poorly understood. We study the magnon dispersion and speci…
Tunneling between chiral magnets: Spin current generation without external fields
Naoya Arakawa
Magnons can generate a spin current, and the standard generating mechanism requires at least one external field. Since this mechanism is often applied to a multilayer system includ…
