Accelerated Quantitative Magnetization Transfer (qMT) Imaging
Quantitative magnetization transfer (qMT) is an advanced magnetic resonance imaging (MRI) technique with enhanced specificity to myelin. The acquisition of many images with unique magnetization transfer (MT) saturation results in a signal response curve known as the z-spectrum. The two-pool tissue …

Remanent magnetization in angrite NWA 4931
… progressively demagnetized to isolate primary magnetization from contaminant overprints and to calculate paleofield intensity. Dust produced during the subsampling process was analyzed to determine that the mineralogical source of the magnetism was magnetite. Analyses of fusion crusted and …

Exploring relaxation of magnetization in paramagnetic molecules
Relaxation of magnetization in paramagnetic molecules consists of several distinct mechanisms that are often difficult to elucidate. The goal of this work is to explore different theoretical approaches to uncovering contributions of different mechanisms to magnetic relaxation. We demonstrated on …

Self-organized magnetization patterns in cold atoms
… reports on a realization of self-organized magnetization patterns in a cloud of cold atoms driven far from equilibrium by a pump laser beam. The experiments are performed in the single mirror feedback configuration, where transverse ordering occurs due to amplification of fluctuations in the …

Diffusion and Magnetization Transfer Studies of Neural Tissue
Our experiments showed that diffusion and magnetization transfer do not offer a unique window to neural function, as had been suggested by some reports in the literature. Rather, our studies taken together with the literature suggest that both these phenomena affect the standard …

CURRENT-INDUCED MAGNETIC FIELD-FREE SWITCHING OF PERPENDICULAR MAGNETIZATION
The spin-orbit torque offers a powerful tool for controlling the magnetic order through electrical current in magnetic materials. Conventional method for field-free switching is complicated. In this thesis, we demonstrate the existence of out-of-plane spin torque in HM/FM bilayer and also a single …

Element-resolved ultrafast magnetization dynamics in ferromagnetic alloys and multilayers
The microscopic origin of ultrafast demagnetization, i.e. the quenching of the magnetization of a ferromagnetic metal on a sub-picosecond timescale after laser excitation, is still only incompletely understood, despite a large body of experimental and theoretical work performed since the discovery …

Chern-Simons theory of magnetization plateaus on the kagome lattice
… Such a system is expected to give rise to magnetization platueaus which can exhibit topological characteristics in certain regimes. We will first develop a flux-attachment transformation that maps the Heisenberg spins (hard-core bosons) onto a problem of fermions coupled to a Chern-Simons …
