Weak ferromagnetism and magnetoelectric coupling in bismuth ferrite [PDF]

open access: yes, 2004
We analyze the coupling between the ferroelectric and magnetic order parameters in the magnetoelectric multiferroic $\mathrm{Bi}\mathrm{Fe}{\mathrm{O}}_{3}$ using density functional theory within the local spin density approximation (LSDA) and the ...

Enhanced Magnetization Switching Efficiency via Orbital‐Current‐Induced Torque in Ti/Ta (Pt)/CoFeB/MgO Structures

open access: yesAdvanced Functional Materials, EarlyView.
The orbital‐current‐induced torque is investigated as an efficient method for controlling magnetization direction. By introducing Ti as an orbital current source in Ti/Ta (or Pt)/CoFeB/MgO structures, the switching current is reduced by ∼25% compared to a conventional spin‐orbit torque structure of Ta/CoFeB/MgO.

Probing the magnetic profile of diluted magnetic semiconductors using polarized neutron reflectivity

open access: yesScientific Reports, 2017
Room temperature ferromagnetism has been observed in the Cu doped ZnO films deposited under an oxygen partial pressure of 10−3 and 10−5 torr on Pt (200 nm)/Ti (45 nm)/Si (001) substrates using pulsed laser deposition.

Effect of Transition Metal Substitution on the Charge-Transfer Phase Transition and Ferromagnetism of Dithiooxalato-Bridged Hetero Metal Complexes, (n-C3H7)4N[FeII1−xMnIIxFeIII(dto)3]

open access: yesCrystals, 2018
The dithiooxalato-bridged iron mixed-valence complex (n-C3H7)4N[FeIIFeIII(dto)3] (dto = dithiooxalato) undergoes a novel charge-transfer phase transition (CTPT) accompanied by electron transfer between adjacent FeII and FeIII sites.

Mesoscopic Ferromagnet/Superconductor Junctions and the Proximity Effect [PDF]

open access: yes, 2000
We have measured the electrical transport of submicron ferromagnets (Ni) in contact with a mesoscopic superconductor (Al) for a range of interface resistances. In the geometry measured, the interface and the ferromagnet are measured separately.

Complex Oxide‐metal Hybrid Metamaterials with Integrated Magnetic and Plasmonic Non‐noble Metal Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A new alloy‐oxide vertically aligned nanocomposite (VAN) thin film with two immiscible non‐noble metal elements of Co and Cu embedded in BaTiO3 (BTO) matrix is designed and fabricated, which presents interesting magnetic, ferroelectric, and optical properties.

Magnetic, electrical and structural properties of annealed ferromagnetic (Zn,Sn)As2:Mn thin films on InP substrates: comparison with undoped ZnSnAs2

open access: yesEPJ Web of Conferences, 2014
We report the magnetic and electrical properties in Mn-doped and undoped (Zn,Sn)As2 epilayers, that were annealed at slightly higher temperatures than the growth temperature.
