Probing Magnetic Polarities of Magnetotactic Bacteria by X-ray Magnetic Circular Dichroism in a Scanning Transmission X-ray Microscope
Magnetotactic bacteria (MTB) are a group of fascinating organisms that can biomineralize chains of nano-scale (~50 nm) single crystals of magnetite (Fe3O4) or greigite (Fe3S4), known as magnetosomes [1]. The magnetosome chain passively aligns the magnetotactic bacteria with the Earth’s geomagnetic field lines, a behaviour called magnetotaxis. This, along with oxygen chemotaxis, is believed to g...
متن کاملA Full Field Transmission X-ray Microscope as a tool for High-Resolution Magnetic Imaging
The XM-1 soft x-ray microscope is a user-dedicated facility located at the Advanced Light Source at Lawrence Berkeley National Laboratory and has recently been established as a tool for high-resolution imaging of magnetic domains. It is a conventional full field transmission microscope which is able to achieve a resolution of 25 nm by using high-presicion zone plates. It uses off-axis bend magn...
متن کاملExperimental investigation of beam heating in a soft X-ray scanning transmission X-ray microscope.
A variable temperature sample holder with an operational range of 15 to 200 °C and an accuracy of ±1 °C has been fabricated for scanning transmission X-ray microscopes (STXM). Here we describe the device, and use it to image the polycrystalline morphology of solid stearic acid and palmitic acid at temperatures near their respective melting points as a means of checking for possible sample heati...
متن کاملQuantitative phase imaging with a scanning transmission x-ray microscope.
We obtain quantitative phase reconstructions from differential phase contrast images obtained with a scanning transmission x-ray microscope and 2.5 keV x rays. The theoretical basis of the technique is presented along with measurements and their interpretation.
