Orbital-Zeeman cross correlation in - and -wave altermagnets
Tomonari Mizoguchi, Soshun Ozaki
Altermagnets are a novel class of magnets that exhibit a large spin splitting but the total magnetic moment is vanishing. This unconventional spin splitting gives rise to various c…
Orbital Magnetism in Honeycomb Ladder
Tomonari Mizoguchi, Soshun Ozaki, Hiroyasu Matsuura
We investigate the orbital magnetic susceptibility of the tight-binding model for the honeycomb ladder with the additional vertical hopping. Despite being one-dimensional, the magn…
Orbital paramagnetism without density of states enhancement in nodal-line semimetal ZrSiS
Soshun Ozaki, Hiroyasu Matsuura, Ikuma Tateishi +2
Unconventional orbital paramagnetism without enhanced density of states was recently discovered in the nodal-line semimetal ZrSiS. We propose a novel interband mechanism, linked to…
Topological contribution to magnetism in the Kane-Mele model: An explicit wave function approach
Soshun Ozaki, Masao Ogata
In our previous publication [S. Ozaki and M. Ogata, Phys. Rev. Research 3, 013058], the quantization of the orbital-Zeeman (OZ) cross term in the magnetic susceptibility, or the cr…
Anomalous Spin Transport Properties of Gapped Dirac Electrons with Tilting
Masao Ogata, Soshun Ozaki, Hiroyasu Matsuura
The anomalous spin transport coefficients of gapped Dirac electrons are studied with application to a quasi-two-dimensional organic conductor -(BETS)I in mind. In the pr…
Universal Quantization of Magnetic Susceptibility Jump at Topological Phase Transition
Soshun Ozaki, Masao Ogata
We examine the magnetic susceptibility of topological insulators microscopically and find that the orbital-Zeeman (OZ) cross term, the cross term between the orbital effect and the…
