Comment on the thermal Hall effect in cuprates
Manfred Bucher
TL;DR
This paper discusses how magnetic moments from different atomic sources in cuprates influence the thermal Hall effect, highlighting the contrasting roles of Cu and O atoms depending on doping type.
Contribution
It provides a new perspective on the magnetic origins of the thermal Hall effect in cuprates based on stripe incommensurabilities and magnetic stability.
Findings
Cu^2+ and Cu atoms support the effect
O atoms from hole doping oppose the effect
Magnetic moments' roles depend on doping type
Abstract
Insights from stripe incommensurabilities and antiferromagnetic stability indicate that the magnetic moments of both host Cu^2+ ions and Cu atoms from electron doping support the thermal Hall effect in cuprates, whereas those of O atoms from hole doping oppose it.
