The Magnetic Origin of the Coherent Order Parameter in Hole-Doped Cuprates

TL;DR

This paper investigates the phase diagram of hole-doped cuprates and presents evidence that the coherent gap has a magnetic origin, scaling with the critical temperature and providing insights into the nature of the order parameter.

Contribution

It proposes that the coherent order parameter in hole-doped cuprates is primarily magnetic in origin, based on analysis of recent neutron scattering data.

Findings

The coherent gap scales with Tc as 2Delta/kTc = 5.4.

The magnetic origin of the order parameter is supported by neutron scattering results.

The phase diagram of hole-doped cuprates is discussed in relation to these findings.

Abstract

The phase diagram for hole-doped cuprates is discussed. By examining some recent inelastic neutron scattering data obtained on hole-doped cuprates we conclude that the coherent gap in hole-doped cuprates has most likely the magnetic origin and scales with Tc, on average, as 2Delta/kTc = 5.4.
