Heusler alloys are theoretically predicted to become half-metals at room temperature (RT).
The advantages of using these alloys are good lattice matching with major substrates, high …

Recent studies have shown that the total magnetic moment in off-stoichiometric Ni–Mn–Ga
alloys depends not only on electronic concentration but also on the degree of chemical …

The unique properties of synchrotron radiation, such as broad energy spectrum, variable
light polarization, and flexible time structure, have made it an enormously powerful tool in …

Abstract Quaternary alloys CoMnCrAl, CoFeCrAl and their ternary counterpart Co 2 CrAl are
studied experimentally and theoretically to explore the effects of the substitution of Mn or Fe …

X-ray magnetic circular dichroism (XMCD) of core-level absorption (x-ray absorption
spectroscopy, XAS) spectra in the soft x-ray region has been measured for the ferromagnetic …

The interface and bulk magnetic properties of epitaxial thin films of the Heusler compounds
Co 2 Cr 0.6 Fe 0.4 Al/Mg/AlO x and CoCr 2 Al/Mg/AlO x are investigated. We compare the …

Ultrafast demagnetization upon excitation with intense laser pulses has been observed for a
variety of ferromagnetic materials. In half‐metals, long demagnetization times are expected …

This thesis is devoted to the study of the exchange interaction and magnetic anisotropies in
thin films of Co {sub 2}-based Heusler compounds with the chemical composition Co {sub 2} …

In this study we investigate the influence of post-growth annealing on different Co 2 Cr 0.6
Fe 0.4 Al samples. We find strong changes in the geometric surface structure as well as in …

How small can an electronic device be and still function? How many atoms are needed for
such device? At what point will the semiconductor fabrication technology be unable to …
