  Two-dimensional van der Waals (2D vdW) materials that display ferromagnetism
and piezoelectricity have received increased attention. Despite numerous 2D
materials have so far been reported as ferromagnetic, developing an air stable
and transferable vdW material that is multiferroic has been challenging. To
address this problem, we report our work on layered transition metal silicates
that are derivatives of kaolinites and lizardites with transition metal
substituting on Al$^{3+}$ and Mg$^{2+}$ sites using ab-initio calculations.
Using Density Functional Theory (DFT), we show that these compounds are stable
under varying O$_2$ partial pressure and can be synthesized using a surface
assisted method. We show that these materials have finite out-of-plane
piezoelectric response thanks to the lack of inversion symmetry and also they
can be tailored to be ferrimagnetic with a non-zero net moment.
