METASTABLE DEEXCITATION SPECTROSCOPY: A NEW PROBE OF SURFACE MAGNETISM
… for probing magnetic and other spin-dependent surface properties. The technique utilizes a He 2 ('3)S(,1) beam in which a plurality of atoms is in one m(,J) level. This electron spin polarized beam has been used to probe the surface magnetic properties of a clean and adsorbate-covered Ni (110) …

A polarized helium ion beam for surface electronic structure studies
… He+ ion beam suitable for use as a- probe of surface electronic structure of metals. The method would represent an extension of ion neutralization spectroscopy (INS), and should provide new information on surface magnetism, electron correlation effects, and the dynamics of the ion …

Spin holography
… spin environment of the electron source atoms in surface magnetism studies. We show that the "vector hologram" obtained by measuring the spin of the emitted electrons, S(scR), can be inverted to give a three-dimensional image of the magnetic environment of the electron emitting source atom. Of …

The 3-D topology of magnetic fields in and around sunspots
The most prominent features on the surface of the solar disc are the sunspots, which have been studied since their detection in the 17th century. Despite this years and centuries of scientific investigations, surprisingly many facets of sunspots are not well understood. In this thesis, the …

Experimental Measurements by Antilocalization of the Interactions between Two-Dimensional Electron Systems and Magnetic Surface Species
… spin-dependent interactions between controllable surface magnetism and itinerant electrons in a non-magnetic host provide insight for spin-based technologies, magnetic data storage and quantum information processing. This dissertation studies two different host systems, an In$_{0.53}$Ga$_{0.47}$As …

Caloric effects in ferroic materials
… larger thermal mass. The second study focused on surface magnetocaloric effect in near stoichiomet- ric Ni-Mn-Ga (NMG) thin films. NMG is interesting as its ferromagnetic transition is accompanied by a structural transition, producing large magnetocaloric effects that can be driven using magnetic …
