Description
The recent isolation of two-dimensional (2D) magnets offers tantalizing opportunities for spintronics, magnonics and quantum technologies at the limit of miniaturization. [1] In this presentation, I will provide an overview of our recent results on this fascinating topic. First, we will take advantage of the outstanding deformation capacity of 2D materials to answer the question: Can we use strain engineering to control spin waves propagation? [2] For that, we will focus on the magnetic properties, magnon dispersion and spin dynamics of the air-stable 2D magnetic semiconductor CrSBr, investigating their evolution under mechanical strain and Coulomb screening using first-principles. Then, we will introduce the modulation of the properties of this 2D magnet after the deposition of molecular materials in a journey towards molecular controlled magnonics. [3–5] On the other hand, we will investigate magnetostriction effects in 2D van der Waals antiferromagnets such as FePS$_3$ and CoPS$_3$, [6] create new Janus 2D magnetic materials based in MPS$_3$ in order to answer: what are the effects of mirror broken symmetry on the magnetic properties? [7], and finally, we will delve into the origin of above-room-temperature magnetism in Fe$_3$GaTe$_2$. [8]
