- Abstract summary: We describe three capabilities which have the potential to seed new directions in magnetism.
By combining these experimental techniques with advanced modeling together with machine learning, we describe how the combination of these domains allows for a new understanding.
We give an outlook for future areas of investigation and the newly developed instruments which will take us there.

- Abstract: With the introduction of x-ray free electron laser sources around the world,
new scientific approaches for visualizing matter at fundamental length and
time-scales have become possible. As it relates to magnetism and
"magnetic-type" systems, advanced methods are being developed for studying
ultrafast magnetic responses on the time-scales at which they occur. We
describe three capabilities which have the potential to seed new directions in
this area and present original results from each: pump-probe x-ray scattering
with low energy excitation, x-ray photon fluctuation spectroscopy, and
ultrafast diffuse x-ray scattering. By combining these experimental techniques
with advanced modeling together with machine learning, we describe how the
combination of these domains allows for a new understanding in the field of
magnetism. Finally, we give an outlook for future areas of investigation and
the newly developed instruments which will take us there.

Dynamic PROPELLER MRI [76.60362295758596]
Off-resonance artifacts in magnetic resonance imaging (MRI) are visual distortions that occur when the actual resonant frequencies of spins within the imaging volume differ from the expected frequencies used to encode spatial information.
We propose to resolve these artifacts by lifting the 2D MRI reconstruction problem to 3D, introducing an additional "spectral" dimension to model this off-resonance.

We show that the quantum interference of transitions induced by radio-wave pumping with longitudinal and radial pulses are able to produce large polarisations at small magnetic fields.
This technique opens the door for a new generation of polarised tracers, possibly low-field MRI with better spatial resolution or the production of polarised fuel to increase the efficiency of fusion reactors.

We develop an in-situ magnetic detection technique at megabar pressures with high sensitivity and sub-microscale spatial resolution.
We observe the macroscopic magnetic transition of Fe3O4 in the megabar pressure range from strong ferromagnetism (alpha-Fe3O4) to weak ferromagnetism (beta-Fe3O4) and finally to non-magnetism (gamma-Fe3O4)
The presented method can potentially investigate the spin-orbital coupling and magnetism-superconductivity competition in magnetic systems.

Electromagnetic (EM) imaging is widely applied in sensing for security, biomedicine, geophysics, and various industries.
It is an ill-posed inverse problem whose solution is usually computationally expensive. Machine learning (ML) techniques and especially deep learning (DL) show potential in fast and accurate imaging.
This article surveys various schemes to incorporate physics in learning-based EM imaging.

We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.
