AI Article Synopsis
- The study examines how hydrostatic pressure affects the magnetic anisotropy energies in (Ga, Mn)As thin films, which have specific magnetic axes due to epitaxial strain.
- Both the in-plane and out-of-plane magnetic anisotropy parameters were found to increase with applied pressure in both types of samples.
- The out-of-plane anisotropy constant aligns with the mean-field p-d Zener model, while the observed changes in uniaxial anisotropy exceed predictions based on the Mn-Mn dimer interactions.
Article Abstract
The impact of hydrostatic pressure on magnetic anisotropy energies in (Ga, Mn)As thin films with in-plane and out-of-plane magnetic easy axes predefined by epitaxial strain was investigated. In both types of sample we observed a clear increase in both in-plane and out-of-plane anisotropy parameters with pressure. The out-of-plane anisotropy constant is well reproduced by the mean-field p-d Zener model; however, the changes in uniaxial anisotropy are much larger than expected in the Mn-Mn dimer scenario.

Motor symptom laterality is an important clinical feature of PD that not only manifests as lateral limb dysfunction but also affects the nonmotor symptoms and the prognosis in PD patients. Previous studies suggested that the compensatory mechanisms in the dominant hemisphere of the brain may be an underlying explanation. The corpus callosum (CC) is the largest fiber connecting the two hemispheres of the brain.

To develop voltage-controlled magnetization switching technologies for spintronics applications, a highly (422)-oriented CoFeSi layer on top of the piezoelectric PMN-PT(011) is experimentally demonstrated by inserting a vanadium (V) ultra-thin layer. The strength of the growth-induced magnetic anisotropy of the (422)-oriented CoFeSi layers can be artificially controlled by tuning the thicknesses of the inserted V and the grown CoFeSi layers. As a result, a giant converse magnetoelectric effect (over 10 s m) and a non-volatile binary state at zero electric field are simultaneously achieved in the (422)-oriented CoFeSi/V/PMN-PT(011) multiferroic heterostructure.

Diffusion-weighted imaging (DWI) has been frequently used to examine age-related deterioration of white matter microstructure and its relationship to cognitive decline. However, typical tensor-based analytical approaches are often difficult to interpret due to the challenge of decomposing and (mis)interpreting the impact of crossing fibers within a voxel. We hypothesized that a novel analytical approach capable of resolving fiber-specific changes within each voxel (i.

Many-body interactions in metal-organic frameworks (MOFs) are fundamental for emergent quantum physics. Unlike their solution counterpart, magnetization at surfaces in low-dimensional analogues is strongly influenced by magnetic anisotropy (MA) induced by the substrate and still not well understood. Here, on-surface coordination chemistry is used to synthesize on Ag(111) and superconducting Pb(111) an iron-based spin chain by using pyrene-4,5,9,10-tetraone (PTO) precursors as ligands.

Objective: The overlap of affective disturbance and psychosis considerably makes it complex to determine the etiology of bipolar disorder (BD) and develop targeted interventions. The present study aimed to determine the white matter microstructural alterations that distinguish between BD with psychosis (BDP) and BD with no psychosis (BDNP) to identify patients who may specifically benefit from appropriately effective treatments.
Methods: Diffusion-weighted magnetic resonance images were acquired from 38 participants with BDP, 52 participants with BDNP and 70 healthy controls (HCs).
