Optical excitation of spin-ordered rare earth metals triggers a complex response of the crystal lattice since expansive stresses from electron and phonon excitations compete with a contractive stress induced by spin disorder. Using ultrafast x-ray diffraction experiments. we study the layer specific strain response of a dysprosium film within a metallic heterostructure upon femtosecon... https://wholesfoodsboxs.shop/product-category/coffee-substitutes/
