Web19 nov. 1983 · This thesis is devoted to experimental studies of magnetism in low dimensions. Being of great fundamental interest, low dimensional magnets support strong quantum uctuations which can result in novel quantum excitations and novel ground states. We used neutron scat-tering technique to study two macroscopic quantum systems: (A) … Webwith an outline of the spin-wave approximation. The concepts of low-dimensional low-spin systems and frustration are discussed with reference to the types of systems covered in this thesis. 1.2 Magnetic Ordering and Excitations The simplest models of magnetic systems are semi-classical descriptions which neglect quantum fluctuations.
