Magnetism in Two Dimensional Phyllosilicates

Activity: Talk or presentation Invited talk

Description

In recent decades, research on two-dimensional (2D) materials has mainly focused on synthetic single crystals from a few material classes. Naturally occurring van der Waals crystals, though largely unexplored, offer greater structural and chemical diversity [1]. Abundant and often non toxic 2D minerals found in soils and clays could support sustainable, biodegradable technologies. Further, the focus of 2D electronics research has largely been on novel semiconductors and spontaneously polarized materials. However, there are far fewer 2D insulators than semiconductors or metals. The entire field relies almost exclusively on hexagonal boron nitride. Surely, this cannot be the only technologically relevant system.

This talk will provide an overview of phyllosilicates' potential applications in 2D electronics, focusing on their magnetic properties [2,3]. We will examine the layered-dependent magnetic response of annite, a rare, naturally occurring iron end member of the mica family (Figure 1). Additionally, we will discuss the potential of using phyllosilicates to manipulate their magnetic response through ion implantation. The goal is to create fully air-stable ferromagnetic insulators with a critical ordering temperature above 300 K.
