Content (Syllabus outline):

Procesiranje magnetnih in drugih intermetalnih kompleksnih zlitin je izjemnega pomena za njihove končne magnetne in druge fizikalne lastnosti. Nanomagnetizem je že zdaj izredno pomemben pri izboljšavi lastnosti magnetnih materialov za uporabo v motorski aplikaciji za električna vozila in vetrne elektrarne. Izjemno pomemben je tudi pri shranjevanju spomina, za senzorsko uporabo in pri izdelavi mehanizmov, strmo pa narašča tudi uporaba v t.i. življenjski znanosti (life-science) in medicini. Izmenjalne interakcije znotraj strukture in interfaznih mej osnovnih magnetnih in drugih kompleksnih intermetalnih zlitin v »bulk« obliki ter nanostruktur, izmenjalna anizotropija, gigantska magnetostrikcija (GMR) in tunelska magnetoupornost (TMR), magnetokalorični efekt, optične lastnosti ter transportne lastnosti elektronov v materialu so lastnosti izrednega tehnološkega pomena. Študij bo delno usmerjen na izdelavo osnovnih materialov s posebnimi lastnostmi ter nano strukturnih materialov, katerih lastnosti se zaradi drugačnih dimenzij, predvsem pa zaradi bistveno večje površine, zelo spremenijo. Poudarek bo na študiju vpliva priprave na končne magnetne in druge fizikalne lastnosti z uporabo različnih fizikalnih metod karakterizacije ter visoko ločljivih analitskih tehnik elektronske mikroskopije. Poudarek pri kemijskem načinu priprave tankih filmov in nano objektov (žice, sfere, cevke) s posebnimi magnetnimi lastnostmi bo na elektrolitski in elektroforetski metodi (ELD, EPD).

Processing of magnetic and other complex intermetallic alloys is exceptionally important in tailoring their final physical properties. Nanomagnetism has already a special role in highly sophisticated methods for improving the magnetic properties of materials for motor application in electric vehicles and wind turbines for clean environment. Nanomagnetism has a special role to play as magnetic properties depend uniquely on both dimensionality and length scales. Nanomagnetism is already central to data storage, sensor and device technologies, but is increasingly being used in the life sciences and medicine. The interlayer exchange interactions within magnetic multilayer structures at interfaces, the static, dynamic and thermal properties of magnetic multilayer and nanostructures, exchange anisotropy, giant
magnetoresistance (GMR) and tunneling magnetoresistance (TMR), magnetocalloric effect,
optical properties, transport properties of electrons are issues of high technological
importance. The emphasis will be on the influence of the processing parameters on tailoring the final magnetic and other physical properties. Fabrication of nanodevices and nanostructures of various materials properties will be studied by a variety of physical methods and high resolution electron microscopy analytical techniques. The study of chemical methods for preparation of magnetic thin films and nano objects (wires, spheres, tubes) will be mainly electrodeposition and electrophoretic deposition (ELD, EPD).
