Low-dimensional magnetic crystals display highly anisotropic interactions between the magnetic moments, yielding interesting magnetic, electronic, and optical properties. The ground and excited states of low-dimensional magnetic systems attract interest with increasing spin dimension and/or decreasing spin values. Materials containing isolated chains might work as models for (1D) S=1/2 Heisenberg systems and Ising spin chains. These models can be used for shedding light on the understanding of magnetic exchange interaction in highly correlated systems. When a geometrical distribution of the magnetic moments is such that it constrains the exchange interactions, the interaction energy is difficult to be minimized, causing the appearance of a complex electronic structure. This often leads to magnetic frustrations. Magnetic frustrations have an impact beyond magnetism, such as multiferroic and high-temperature conductivity behaviors.
