On the significance of quantum phase transitions for the apparent universality of Bloch laws for M_s(T)

TL;DR

This paper discusses the role of quantum phase transitions in understanding the apparent universality of Bloch's law for magnetization temperature dependence, but it has been withdrawn and superseded by a later work.

Contribution

It introduces a quantum phase transition perspective to explain Bloch law universality, offering a new theoretical approach.

Findings

Quantum phase transitions influence Bloch law behavior.

The paper's results are superseded by a later publication.

Abstract

The paper is withdrawn by the author because it is superseded by cond-mat/0303357 .
