Transport and Magnetic Properties of FexVse2 (x = 0 - 0.33)

TL;DR

This study investigates how iron intercalation affects the structural, transport, and magnetic properties of 1T-VSe2, revealing suppression of charge density waves and the emergence of a new transition at higher Fe concentrations.

Contribution

It provides new insights into the effects of Fe intercalation on 1T-VSe2, including the suppression of CDW and the discovery of a first order transition at higher Fe levels.

Findings

Suppression of the 110K charge density wave transition.

Emergence of a new transition at 160K with increased Fe.

Fe intercalation does not induce magnetism in 1T-VSe2.

Abstract

We present our results of the effect of Fe intercalation on the structural, transport and magnetic properties of 1T-VSe2. Intercalation of iron, suppresses the 110K charge density wave (CDW) transition of the 1T-VSe2. For the higher concentration of iron, formation of a new kind of first order transition at 160K takes place, which go on stronger for the 33% Fe intercalation. Thermopower of the FexVSe2 compounds (x = 0 - 0.33), however do not show any anomaly around the transition. The intercalation of Fe does not trigger any magnetism in the weak paramagnetic 1T-VSe2, and Fe is the low spin state of Fe3+.
