Electronic Correlations in Vanadium Revealed by Electron-Positron Annihilation Measurements
Josef Andreas Weber, Diana Benea, Wilhelm H. Appelt +6
The electronic structure of vanadium measured by Angular Correlation of electron-positron Annihilation Radiation (ACAR) is compared with the predictions of the combined Density Fun…
Positron spectroscopy of point defects in the skyrmion-lattice compound MnSi
Markus Reiner, Andreas Bauer, Michael Leitner +7
Outstanding crystalline perfection is a key requirement for the formation of new forms of electronic order in a vast number of widely different materials. Whereas excellent sample…
Spin-resolved Fermi surface of the localized ferromagnetic Heusler compound CuMnAl measured with spin-polarized positron annihilation
Josef A. Weber, Andreas Bauer, Peter Böni +7
We determined the bulk electronic structure in the prototypical Heusler compound CuMnAl by measuring the Angular Correlation of Annihilation Radiation (2D-ACAR) using spin-pola…
Electron-electron interaction strength in ferromagnetic nickel determined by spin-polarized positron annihilation
Hubert Ceeh, Josef-Andreas Weber, Peter Böni +7
The two-photon momentum distribution of annihilating electron-positron pairs in ferromagnetic nickel (Ni) was determined by measuring the spin-polarized two-dimensional angular cor…
First 2D-ACAR Measurements on Cu with the new Spectrometer at TUM
Josef Andreas Weber, Peter Boni, Hubert Ceeh +2
The two-dimensional measurement of the angular correlation of the positron annihilation radiation (2D-ACAR) is a powerful tool to investigate the electronic structure of materials.…
First measurements with the Munich 2D-ACAR spectrometer on Cr
Hubert Ceeh, Josef Andreas Weber, Michael Leitner +2
The Munich 2D-ACAR spectrometer at the Maier-Leibnitz accelerator laboratory in Garching has recently become operational. In the present implementation a 2D-ACAR spectrometer is se…
