   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; neutron powder diffraction; magnetometry; layered magnetic structure; incommensurate helical structure; ThCr2Si2 type structure; antiferromagnetism; ferromagnetism; electronic structure calculations; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : Thin metal films have found their use in many magnetic devices. They form pseudo two-dimensional systems, where the mechanisms for the magnetic interactions between the layers are not completely understood. LÄS MER

3. 2. Magnetic frustration and low-dimensional magnetism : in transition metal fluorophosphates and square-lattice intermetallic compounds

   Sammanfattning : Solids can display a variety of vastly different magnetic properties. Besides the generally well known ferromagnets, antiferromagnets with their antiparallel arrangements of magnetic moments can exhibit a wide range of complex magnetic behavior such as magnetic frustration or low-dimensional antiferromagnetism.
