Electrostatic Tem Studies Of Magnetic Domains In Thin Iron Films, Hideaki Karamon
Electrostatic Tem Studies Of Magnetic Domains In Thin Iron Films, Hideaki Karamon
Dissertations and Theses
An electron microscope with electrostatic lenses was used for high resolution studies of magnetic domains in thin iron films.
Observation methods used to determine the directions of local magnetization in iron thin films were the Lorentz method and the Foucault method.
We studied how Bloch line-crosstie pairs and crosstie main walls behave in applied, in-plane magnetic fields. We found that crosstie main walls remain unchanged until crosstie density goes nearly to zero when the field is applied perpendicular to the main wall. A twisted type of domain appears where crossties disappear.
Effective Force Constant Ratios: Iron In Iridium And Rhodium, Dennis Munsterman
Effective Force Constant Ratios: Iron In Iridium And Rhodium, Dennis Munsterman
Dissertations and Theses
Classical methods of analyzing heat capacity data for the characteristic moments of the frequency distribution are applied to iridium and rhodium. Impurity moments are determined from high and low temperature f values. These moments are combined by modern theory to estimate the magnitude of the host-host to host-impurity force constant ratio. Ratios of the various host moments are also examined.
