# Suppression of long range magnetic ordering and electrical conduction in Y$_{1.7}$Bi$_{0.3}$Ir$_2$O$_7$ thin film

## TL;DR

This study demonstrates that Y$_{1.7}$Bi$_{0.3}$Ir$_2$O$_7$ thin films lack long-range magnetic order and show suppressed electrical conduction due to mixed Ir oxidation states and magnetic inhomogeneity.

## Contribution

It reveals the suppression of magnetic ordering and conduction in Y$_{1.7}$Bi$_{0.3}$Ir$_2$O$_7$ thin films, highlighting the role of mixed Ir oxidation states and magnetic inhomogeneity.

## Key findings

- Absence of long-range magnetic order in the thin film.
- Suppressed electrical conduction linked to Ir oxidation states.
- Presence of Griffiths-like magnetic phase below 168K.

## Abstract

We find that the long-range magnetic ordering is absent and electrical conduction suppressed in Y$_{1.7}$Bi$_{0.3}$Ir$_2$O$_7$/YSZ(100) thin film prepared by pulsed laser deposition. The sharp down-turn of inverse magnetic susceptibility X-1(T) from the conventional Curie-Weiss behaviour below T* ~ 168K suggests an inhomogeneous ferromagnetic Griffiths like phase. The transport and magnetic properties are explained on the basis of the coexistence of mixed oxidation states of Ir, (i.e. Ir4+ and Ir3+) leading to non-magnetic defects and reduction in t2g density of states at the Fermi level.
