Important results from the project
In this project, we have wanted to use synchrotron X-ray and neutron scattering based techniques to characterize magnetic materials that are important for the continued development of green technology and future energy technologies with a focus on magnetic cooling applications and renewable energy generation. Another objective is to train and educate young researchers in the use of synchrotron X-ray and neutron scattering techniques that are available at large-scale research facilities. With some exceptions due to the pandemic, the the goals have been achieved.
Expected long term effects
1. The high-entropy alloy AlCoCrFeNiMnx were characterized by performing synchrotron measurements in Germany at DESY, Petra III. The results have been published in Journal of Alloys and Compounds. 2. Temperature dependent neutron diffraction measurements have been performed at ISIS on the magnetic material CeFe(12-x)Mnx (x=5,7). The data will be used to determine the magnetic structure for the materials. 3. The WISH neutron diffractometer at ISIS has been used to determine the magnetic structure of Co3Mn20B6.
Approach and implementation
The project has consisted of three parts: i) Application of beamtime for neutron diffraction measurements at ISIS and synchrotron X-ray diffraction measurements at at DESY, Petra III. ii) Performing measurements on site at the large scale research facilities. iii) Analysis of results at the Ångström laboratory. The project parts have with one exception been implemented with good results; due to the pandemic, the neutron diffraction measurements were carried out by beamline scientists at ISIS.
