A first principles study of iron doping in Ni2CoGa magnetic shape memory alloy

AIP Advances, 2015
First principles calculations have been performed for the Ni2Co1-xFexGa Heusler compound in order to investigate the nature of structural instability and the effect of iron doping in enhancing the magneto-structural properties. Calculations show that the

Weak In‐Plane Ferromagnetism and Electronic Nematicity in the Distorted Triple‐Q Magnetic Phase of Co1/3TaS2

Advanced Materials, EarlyView.
Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

On magnetic shape memory alloy actuator characteristics

Journal of Vibroengineering, 2009
Magnetic shape memory alloys (MSMA) are adaptive materials controlled with a magnetic field. A fast response, large magnetic field induced strain and high damping make MSMAs attractive materials for actuators. The aim of this study was to define the characteristics of a MSMA actuator and evaluate its suitability for vibration control.

Kinetics of martensitic transformations in magnetic field or under hydrostatic pressure

Science and Technology of Advanced Materials, 2011
We have recently constructed a phenomenological theory that provides a unified explanation for athermal and isothermal martensitic transformation processes. On the basis of this theory, we predict some properties of martensitic transformation and confirm

Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures

Advanced Materials, EarlyView.
An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
