Observation of Magnetic Head Fields Using Distorted Transmission Electron Microscopy Images

Abstract: Density functional theory calculations on Ybusing the Hartree Fock system and the analogous Dirac-Hartree-Fock methods predict that Ybis stable in the Py,z state. The electron affinity obtained after the correlation energy functionals used are calibrated against Caand Lu is 2f 1 mHartree (54+ 27 meV).The calculations indicate that the Pilz state is unlikely to be bound due to spin-orbit coupling reducing its binding energy.It had long been thought that atoms with closed subshells such &s Ca, Sr, Ba and Ra (who… Show more

“…One advantage of the TIE method is that it may be used to recover the information on the phase beyond the sample, thus giving it the ability to map stray fields. Stray fields may also be measured in the TEM-DPC method, but only when they exist over a suitable substrate material, or where the microscope is modified to incorporate a patterned film or mask (Suzuki et al, 1997, 2000; Shimakura et al, 2003; Sasaki et al, 2010).…”

“…This was understood in some of the earliest work on quantifying the magnetization distribution of samples from their induction in a TEM (Fuller & Hale, 1960), but direct use of the real-space deflection information has been rare in the decades since then. Indeed, only a small number of reports of its use have been made, and these used a modified TEM, where a patterned film or shadow mask was incorporated to allow stray magnetic (Wade, 1976; Suzuki et al, 1997, 2000; Shimakura et al, 2003) and electric (Sasaki et al, 2010) fields to be mapped in vacuum. When used in tomographic applications, this technique has been labeled “projected electron magnetic tomography” (PEMT; Shimakura et al, 2003).…”

“…The technique, which we refer to as TEM-differential phase contrast (TEM-DPC), has origins dating back decades (Fuller & Hale, 1960), but has gone largely unused since then. In part, this is because previous approaches have used patterned films or shadow masks to form texture suitable for assessing the image distortions, which required a modification of the microscope and limited mapping to stray magnetic (Wade, 1976;Suzuki et al, 1997Suzuki et al, , 2000Shimakura et al, 2003) and electric fields (Sasaki et al, 2010) beyond the sample. Another reason is the tremendous success since its early adoption in electron microscopy (Bajt et al, 2000;De Graef & Zhu, 2001) of methods for phase recovery through solving the transport-of-intensity equation (TIE) (Teague, 1983).…”
