Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

A Multiphysical Field Dynamic Behavioral Model of Perpendicular STT-MTJ

IET Circuits, Devices and Systems
The spin transfer tunnel magnetic tunnel junction (STT-MTJ) has been widely used in computers, memory, and other fields because of its nonvolatility, low power consumption, and high capacity for integration, attracting significant attention in recent ...

Tunnel magnetoresistance effect in a magnetic tunnel junction with a B2-Fe3Sn electrode

AIP Advances, 2019
In magnetic tunnel junctions (MTJs), the tunnel resistance varies as a function of the relative magnetic configuration of the electrode, in an effect called tunnel magnetoresistance (TMR).

Realization of quantum diffraction of a thermal flux

, 2013
The first evidence of the dc Josephson effect dates back to 1963 when J. S. Rowell measured the diffraction pattern of the critical current flowing through a single superconducting tunnel junction subjected to an in-plane magnetic field.

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Atomistic Model of Magnetic Tunnel Junction Spin-Torque Nano-Oscillators

IEEE Access
We have developed a model of a CoFeB/MgO magnetic tunnel junction nano-pillar for application as a spin torque nano-oscillator (MTJ-STNO) using an atomistic model combined with a spin accumulation model.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

Advanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

0-pi Josephson tunnel junctions with ferromagnetic barrier

, 2006
We fabricated high quality Nb/Al_2O_3/Ni_{0.6}Cu_{0.4}/Nb superconductor-insulator-ferromagnet-superconductor Josephson tunnel junctions. Using a ferromagnetic layer with a step-like thickness, we obtain a 0-pi junction, with equal lengths and critical ...
