Three dimensional magnetic systems hold the promise to provide new functionality associated with greater degrees of freedom. Over the last years we have worked towards developing methods to fabricate and characterize three dimensional magnetic structures. Specifically, we have combined X-ray magnetic imaging via circular dichroism (XMCD) with new iterative reconstruction algorithms to achieve...
SoftiMAX is a soft X-ray spectro-microscopy beamline at MAX IV Laboratory, the Swedish national synchrotron center in Lund, Sweden. It is situated at the 3 GeV ring at MAX IV and provides a very high average coherent flux owing to the low emittance properties of the ring1,2.
SoftiMAX consists of two branch lines utilizing different focusing solutions and catering to various imaging methods....
Amorphous rare-earth transition-metal (RE-TM) ferrimagnets are workhorse materials in the field of spintronics. Developed chiefly for magneto-optical recording and bubble memories in the second half of the 20th century, they have remained at the forefront of the field, for example because they allow for ultrafast all-optical switching1, ultrafast current-driven domain wall motion2, and easy,...
Magnetic skyrmions exhibit a rich landscape of dynamical behavior shaped by their topological character and collective organization. In this work, we explore the motion of skyrmion lattices in chiral magnets under two orthogonal driving mechanisms: magnetic field gradients [1] and thermal gradients [2,3]. Using resonant elastic x-ray scattering (REXS) on Cu$_2$OSeO$_3$, we demonstrate how...
The question of fluctuation and population growth at the local level and how that influences global properties has been studied extensively in physical, biological and social sciences. In quantum material interplay of fluctuation and phase transitions provide deep insight into the phase transition pathways. Using coherent x-ray scattering we have shown that phase transition in amorphous FeGe...
