Multiple frustration-induced plateaus in a magnetization process of the mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain

TL;DR

This paper investigates the magnetization behavior of a mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain, revealing multiple plateaus caused by frustration when certain interaction ratios are exceeded.

Contribution

It introduces an exact analytical approach to identify multiple frustration-induced magnetization plateaus in a complex quantum spin system.

Findings

Multiple magnetization plateaus appear with high frustration levels.

Single plateau occurs when the Heisenberg interaction is weak.

Analytical methods effectively describe the system's magnetic behavior.

Abstract

Magnetization process of the mixed spin-1/2 and spin-3/2 Ising-Heisenberg diamond chain is examined by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation and transfer-matrix method. Multiple frustration-induced plateaus in a magnetization process of this geometrically frustrated system are found provided that a relative ratio between the antiferromagnetic Heisenberg- and Ising-type interactions exceeds some particular value. By contrast, there is just a single magnetization plateau if the frustrating Heisenberg interaction is sufficiently small compared to the Ising one.
