Doping Dependence of the in-Plane Transition in Co$_3$Sn$_2$S$_2$

TL;DR

This study investigates how doping with indium affects the magnetic phase transitions in Co$_3$Sn$_2$S$_2$, revealing a shared energy scale underlying both the ferromagnetic and in-plane magnetic transitions.

Contribution

It demonstrates that doping influences both magnetic transitions in a correlated manner, suggesting a common underlying energy scale in Co$_3$Sn$_2$S$_2$.

Findings

Both transitions decrease with In doping.

Transitions follow the same doping dependence.

Indicates a single energy scale governs both processes.

Abstract

In Co$_3$Sn$_2$S$_2$ two transitions are observed, the main one to a ferromagnetic state at $T_C = 174$ K and the second one, involving in-plane components at $T_P = 127$ K. We follow their doping dependence as Sn is replaced with In, which causes a reduction of $T_C$ and $T_P$. Importantly, both transitions follow the same doping dependence, indicating a single energy scale involved with both processes.
