Abstract: The family of 2D compounds has grown almost exponentially since the
discovery of graphene and so too the rapid exploration of their vast
range of electronic properties. Some family members include
superconductors, Mott insulators with charge-density waves, semimetals
with topological properties, and transition metal dichalcogenides with
spin-valley coupling. Among several compounds, the realization of
long-range ferromagnetic order in van der Waals (vdW) layered materials
has been elusive till very recently. Long searched but only now
discovered 2D magnets are one of the select group of materials that
retain or impart strongly spin correlated properties at the limit of
atomic layer thickness.In this presentation I will discuss how different
layered compounds(e.g. CrX3(X=F, Cl, Br, I), VI3, MnPS3,Fe3GeTe2,
FePS3, CrGeTe3)can providenew playgrounds for exploration of spin
correlations involving quantum-effects, topological spin-excitationsand
higher-order exchange interactions. I will show that this new generation
of vdWmagnets can help to revolutionizeseveral technological
applications from sensing to data storage, which can lead to new
magnetic, magnetoelectric and magneto-optic applications in industry.
Moreover, I will discuss some challenges at the forefront of 2D vdW
magnets and new opportunities to understand fundamental problems.
