Abstract: Artificial spin ice is a system of highly shape anisotropic dipolar coupled magnetic nanostrutcures
arranged in a special geometry leading to geometric frustration in the system. Due to the strong
shape anisotropy, these nanostructures are considered as behaving like a macrospins. The dipolar
interaction among the nanomagnets (macrospins) leads to a certain arrangement of macrospins
which mimic the behavior of position of protons in water ice. An excitation from ground state in
these systems leads to magnetically charged states which behave like Dirac monopoles. Such
monopoles are found to appear in pairs of oppositely charged vertices and are randomly created in
the network of the nanostructures providing an opportunity to study behavior of magnetic
monopoles in solid state systems. In this talk, I will discuss these properties of such magnetically
charged vertices and will show that such vertices can be predictively created in finite size ASI
systems.
