Magnetic moment centers in titanium dioxide photocatalysts loaded on reduced graphene oxide flakes

Reviews on Advanced Materials Science, 2021
A whole series of titania nanocomposites modified with reduced graphene oxide (rGO) was prepared using solvothermal method followed by calcination. Modification of titania with rGO has been found to lead to better photocatalytic properties.

Theory of the spin-torque-driven ferromagnetic resonance in a ferromagnet/normal-metal/ferromagnet structure

, 2006
We present a theoretical analysis of current driven ferromagnetic resonance in a ferromagnet/normal-metal/ferromagnet tri-layer. This method of driving ferromagnetic resonance was recently realized experimentally by Tulapurkar et al.

Acoustically driven ferromagnetic resonance

, 2011
Surface acoustic waves (SAW) in the GHz frequency range are exploited for the all-elastic excitation and detection of ferromagnetic resonance (FMR) in a ferromagnetic/ferroelectric (nickel/lithium niobate) hybrid device.

Creation of Materials Based on Novel Principles Utilizing an Interaction between Magnetism and Electromagnetic Waves —Dynamic Permeability of Magnetoplumbite-structured Ferrite with an In-plane Magnetic Anisotropy Through the Controlled-particle Orientations—

Electrochemistry, 2020
We prepared a high-quality magnetic BaCoTiFe10O19 ferrite-based composite sheet and BaCoTiFe10O19 thin films exhibiting in-plane magnetic anisotropy. In-plane magnetic anisotropy was realized by controlling particle orientation to achieve high-resonance ...

Anomalous behavior of spin wave resonances in Ga_{1-x}Mn_{x}As thin films

, 2003
We report ferromagnetic and spin wave resonance absorption measurements on high quality epitaxially grown Ga_{1-x}Mn_{x}As thin films. We find that these films exhibit robust ferromagnetic long-range order, based on the fact that up to seven resonances ...

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

Advanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.
