Spin Freezing and Melting in Na$_{0.5}$CoO$_{2}$

TL;DR

This paper investigated spin freezing and melting phenomena in Na$_{0.5}$CoO$_{2}$, but was withdrawn due to sample issues, limiting conclusive findings.

Contribution

The study aimed to explore magnetic phase transitions in Na$_{0.5}$CoO$_{2}$, but was withdrawn because of sample phase problems, providing limited new insights.

Findings

Sample was a mixed phase, affecting results

Study was withdrawn, no definitive conclusions

Highlights importance of sample purity in magnetic studies

Abstract

This paper has been withdrawn. The sample was a mixed phase.
