Query: Magnetoelastic Coupling in Hole-doped Two-dimensional \b{eta}-PbO   The realization of intertwined ferroelasticity and ferromagnetism in
two-dimensional (2D) lattices is of great interest for broad nanoscale
applications, but still remains a remarkable challenge. Here, we propose an
alternative approach to realize the strongly coupled ferromagnetism and
ferroelasticity by carrier doping. We demonstrate that prototypical 2D
\b{eta}-PbO is dynamically, thermally and mechanically stable. Under hole
doping, 2D \b{eta}-PbO possesses ferromagnetism and ferroelasticity
simultaneously. Moreover, the robustness of ferromagnetic and ferroelastic
orders are doping tunable. In particular, 2D \b{eta}-PbO features in-plane easy
magnetization axis that is coupled with lattice direction, enabling
ferroelastic manipulation of spin direction. Our work highlights a new
direction for 2D magnetoelastic research and enables the possibility for
multifunctional devices.
