Electrostatic TEM studies of magnetic domains in thin iron films

Karamon, Hideaki 01 January 1980 (has links)
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.

Study of a ferromagnetic semiconductor by the scanning Hall probe microscope

Kweon, Seongsoo, 1967- 18 September 2012 (has links)
The primary goal of my dissertation was to build a Scanning Hall Probe Microscope (SHPM) for studying the domain structure of a ferromagnetic semiconductor (Ga[subscript 0.94]Mn[subscript 0.06]). This new semiconductor may be used in the emerging field of spintronics, where both the charge and spin of an electron are utilized. The first part of this dissertation introduces the scanning probe microscopy techniques that are used for our homemade SHPM performance test and images. In chapter 2, general spintronics and ferromagnetic semiconductor are introduced. A compact design of our LT-SHPM is introduced in chapter 3. A unique taper seal based on stainless steel and Cu for opening/closing the vacuum chamber is used for our homemade SHPM. In chapter 4, Hall probes are discussed. In this chapter, ESD (Electrostatic discharge) and its repair work are discussed. Finally, in Chapter 5, SHPM imaging results of Ga[subscript 0.94]Mn[subscript 0.06]As are discussed. We observed stripe domain patterns. We also observed the domain patterns as a function of magnetic field and temperature. / text
