Artificial spin ice (ASI) systems have emerged as powerful platforms for exploring the
fundamental aspects of magnetic frustration and topological phenomena in condensed …

The interplay between topology and energy hierarchy plays a vital role in the collective
magnetic order in artificial ferroic systems. Here we investigate, experimentally, the effect of …

We demonstrate the presence of an emergent magnetic anisotropy in square lattices of
circular mesospins. An external field is used to saturate the magnetization along the [10] and …

Metallic disks engineered on the 100 nm scale have an internal magnetic texture which
varies from a fully magnetized state to a vortex state with zero moment. The interplay …

We provide experimental and numerical evidence for thermal excitations within and among
magnetic mesospins, forming artificial spin ice structures. At low temperatures, a decrease in …

We investigate the design of magnetic ordering in one-dimensional mesoscopic magnetic
Ising chains by modulating long-range interactions. These interactions are affected by …

We demonstrate the controlled generation and annihilation of (anti) skyrmions with tunable
chirality in magnetic heterostructures by means of micromagnetic simulations. By making …

We numerically study a mesoscopic system consisting of magnetic nanorings in the
presence of thermal magnetization fluctuations. We find the formation of dipolar-field …

Magnetotoroidal order, also called ferrotoroidicity, is the most recently established type of
ferroic state. It is based on a spontaneous and uniform alignment of unit-cell-sized magnetic …

In this thesis, the interplay between the inner textures and island-island interactions is
explored, anticipating the emergence of behavior beyond that of conventional universality …
