Aberration Correction in Electron Microscopy
... resolution limit of about 0.25 nm, which does not suffice to resolve individual atoms of non-periodic objects. Since we cannot significantly increase the acceleration voltage, we must eliminate or sufficiently reduce spherical and chromatic aberrations. One can largely suppress the chromatic aberrat ...

Spin Hamiltonians and Exchange interactions
... may consider a spin as having a definite direction, just as in the limit of small ~ we may consider an object as having both position and momentum well-defined. Semiclassical spin dynamics This result below can be thought of as the analog for spins of Newton’s equations; the condition for static equ ...

Flatland Electrons in High Magnetic Fields
... Electrons in a “flatland” are amazing! A simple low-temperature measurement of the resistance of a two-dimensional electron system (2DES) as a function of perpendicular magnetic field (B) reveals why (Fig. 1). In this figure the resistivities along (ρxx ) and perpendicular (ρxy ) to the direction of ...

The phase and chirp of each of the electron pulses can be measured through interference with a reference electron pulse if the time dependence of the ejected electron flux is measured and if the reference electron pulse is not highly chirped. In the experiment, ...

Electron paramagnetic resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.
