Low- and high-field induced uniform and staggered magnetizations of a spin ladder with DM term

TL;DR

This paper derives analytical formulas for uniform and staggered magnetizations in a spin ladder with Dzyaloshinskii-Moriya interaction, describing magnetic behavior in low and high magnetic field regimes.

Contribution

It provides the first analytical expressions for magnetizations in a spin ladder with DM interaction in different magnetic field regimes.

Findings

Formulas accurately describe magnetic behavior at low and high fields.

Magnetization behavior varies significantly between the two regimes.

Analytical results align with known physical properties.

Abstract

Analytic expressions for uniform and staggered magnetizations of a spin ladder with a staggered Dzyaloshinskii-Moriya interaction along rungs are obtained in the lowest perturbative orders. The obtained formulas describe magnetic behavior in two marginal regions related to low ($h\ll h_c$) and high ($h\gg h_s$) magnetic fields.
