ArXiv

Analysis

This paper investigates the magnetic properties of the TbAgAl compound under high magnetic fields. The study extends magnetization measurements to 12 Tesla and resistivity measurements to 9 Tesla, revealing a complex magnetic state. The key finding is the observation of a disordered magnetic state with both ferromagnetic and antiferromagnetic exchange interactions, unlike other compounds in the RAgAl series. This is attributed to competing interactions and the layered structure of the compound.

Key Takeaways

•Extended magnetization and resistivity measurements on TbAgAl to high fields.
•Identified a disordered magnetic state with both ferromagnetic and antiferromagnetic interactions.
•Observed a metamagnetic transition from antiferromagnetic to ferromagnetic state.
•Attributes the disordered state to competing interactions and the layered structure.

Reference

“The field dependence of magnetization at low temperatures suggests an antiferromagnetic state undergoing a metamagnetic transition to a ferromagnetic state above the critical field.”
