Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review
Metals, 2021 Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic fields. Since the deformation

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1949 The problem of neutron diffraction by crystals is treated by analogy with X-ray diffraction, consideration being given to the perfect crystal, the mosaic crystal and the powdered block. The first part of the paper deals with a comparison between X-ray and neutron diffraction and it is shown that quantitatively the two are similar, apart ...
