Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Fe–Pt films prepared from plating baths containing glycine as a complexing agent

open access: yesAIP Advances
We have reported Fe–Pt films with hard magnetic properties electroplated from plating baths using citric acid as a complexing agent. The present study focuses on glycine as a new complexing agent instead of citric acid.

Exploration of the Reduction Diffusion Temperature for Different Phases of Samarium–Cobalt Magnetic Particles

open access: yesMolecules
We report a method for synthesizing different phases of samarium–cobalt particles through microwave-assisted combustion combined with high-temperature reduction and diffusion, and identify the optimal temperature for forming the 1:5 phase using this ...

Co-rich cobalt platinum nanowire arrays: effects of annealing [PDF]

open access: yes, 2005
The effects of annealing on the crystal structure and magnetic properties of Co-rich cobalt platinum nanowire arrays embedded in anodic aluminium oxide membranes have been investigated. For this purpose, a rapid thermal annealing to temperatures of 300 &#

Understanding and Tuning Mobile Interfaces in Ferroelectric Hf0.5Zr0.5O2 Thin Films in Relation to Microstructure

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

Global weak solutions to degenerate coupled transport processes in partially saturated deformable elastic-inelastic porous media

open access: yesElectronic Journal of Differential Equations, 2020
In this work we prove the existence of global weak solutions to a degenerate and strongly coupled parabolic system arising from the transport processes through partially saturated deformable porous materials.

Effect of Annealing Temperature and Composition on Magnetic Properties of Manganese-Bismuth Homogenized in Tube Furnace [PDF]

open access: yesIranian Journal of Materials Science and Engineering, 2022
Repeated heat treatment on manganese-bismuth (MnBi) in a tube furnace increases the homogeneity of rare-earth-free magnets. Ferromagnetic low temperature phase (LTP) MnBi is formed after heating Mn and Bi in a ratio of 2:1 at 1000 °C for 1 h and then 400

Coercive Distribution [PDF]

open access: yes, 2018
Canonical theories of political economy struggle to explain patterns of distribution in authoritarian regimes. In this Element, Albertus, Fenner, and Slater challenge existing models and introduce an alternative, supply-side, and state-centered theory of 'coercive distribution'.

Magnetism and effect of anisotropy with one dimensional monatomic chain of cobalt by a Monte Carlo simulation

open access: yes, 2007
The magnetic properties of the one dimensional (1D) monatomic chain of Co reported in a previous experimental work are investigated by a classical Monte Carlo simulation based on the anisotropic Heisenberg model.

Gram‐Scale Production of Iron Oxide Rubik‐Cube Nanoparticles: New Tools for the Clinical Translation of Magnetic Hyperthermia and Magnetic Particle Imaging

open access: yesAdvanced Functional Materials, EarlyView.
This work reports the first gram‐scale solvothermal synthesis of ‘Rubik's cube’ nanoparticles—cubic, dendritic multicore structures with tuneable sizes and exceptional magnetic heating performance. Featuring iron oxide single‐domain character, with low coercivity fields, high magnetization, and strong MPI signals, they enable viscosity‐independent ...
