This book presents analytic and numerical studies of magnetism in strongly correlated solid-state systems. Competing tendencies in these systems can lead to spontaneous nanoscale structures, such as stripes and checkerboards. There are three topics explored in this book. First, spin waves and magnetic excitations for well-ordered spin structures are studied by using a suitably parametrized Heisenberg model. Both site-centered and bond-centered antiphase domain walls are considered for a range of spacings between stripes and checkerboard antiphase domain walls. Second, quasi-two-dimensional...
