Ising systems are the one most actively studied problems in statistical physics and
condensed matter physics, and they have been used to explain many important cooperative physical
systems. In this talk, first I will briefly introduce Ising systems and then emphasis their importance in
statistical physics and condensed matter physics with two subjects. The first one, I will elucidate how
to obtain metastable and unstable phases or states that are very important in many experimental and
theoretical works. The second one, I will demonstrate that Ising models play important role in very
interesting subject of the dynamic phase transition and dynamic phase diagrams. Next, I will provide
an overview of recent and important works on properties of magnetic nanostructures studied by Ising
systems. In particular, I will present the hysteresis, coercivity and compensation behavior of Ising
nanostructures and compared with some experimental works. Finally, I will briefly review and
discuss the dynamic magnetic properties of the Ising nanostructures.
