Magnetic ptoperties of the nanocomposite materials

Ing. Mgr. Aleš Hendrych Palacky University, Olomouc, December 2009 Supervisor: Doc. RNDr. Roman Kubínek, CSc. Magnetic properties of the nanocomposite materials An enormous advancement in magnetic nanomaterial research during last two decades has been achieved. Much of the effort has been paid to the fundamental physical aspects arising from the preparation process. New trends mainly in the area of information, data storage and sensor technologies are pushing up the development of new magnetic materials to nanometer dimensions. There is still a challenge to meet on the field of the nanomaterials because only in user-specific control limited success was reached so far. Many parameters that affect the final material composition including heat treatment and straining effects should be taken into account due to feasibility of tuning or perking up magnetic nanostructured materials. Thoroughly performed scientific investigations are needed in order to successfully describe and clarify newly developed systems. Naturally, such investigations have to be realized by delicate measuring methods. Therefore, this thesis is dedicated to the development of the particular techniques, namely magneto-optical methods, magneto-optical vector magnetometry, Kerr microscopy and magnetic force microscopy, which are..
