Topological piezomagnetic effect in two-dimensional Dirac quadrupole altermagnets
H. Radhakrishnan, B. Bell, C. Ortix +1
Altermagnets provide a natural platform for studying and exploiting piezomagnetism. In this paper, we introduce a class of insulating altermagnets in two dimensions (2D) referred t…

Layer dipole magnetoelectric polarizability of antiferromagnetic bilayers
H. Radhakrishnan, C. Ortix, J. W. F. Venderbos
In this paper we study magnetoelectric effects in two-dimensional magnetic bilayers and introduce the notion of a layer dipole magnetoelectric polarizability. This magnetoelectric…
