Resonances in Ferromagnetic Gratings Detected by Microwave Photoconductivity

, 2005
We investigate the impact of microwave excited spin excitations on the DC charge transport in a ferromagnetic (FM) grating. We observe both resonant and nonresonant microwave photoresistance.

Automation of ferromagnetic resonance spectrometer

Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2016
A method of ferromagnetic resonance (FMR) is described. It has been verified and substantiatied that the parameters of FMR can be used for studying of dislocation structure of surface of ferromagnetics at depth of 10-6-10-7 m.

Substitution effects on magnetic properties of Mg1.3-xMnxAlyFe1.8-yO4 ferrite

AIP Advances, 2017
Mg1.3-xMnxAlyFe1.8-yO4 (x = 0.1–0.2, y = 0.15–0.3) spinel ferrites were prepared using conventional ceramic technique. Highly densified Mg–Mn–Al ferrites (with 99% theoretical density) were obtained, and the influence of Mn and Al substitution on the ...

FERROMAGNETICS IN MAGNETIC RESONANCE IMAGING [PDF]

Proceedings on Engineering Sciences, 2019
Useful tool in diagnostic radiology is magnetic resonance imaging (MRI). Scanning with this system can cause interaction between ferromagnetic used for creation of implants and magnetic fields of MRI. In order to determine magnetic field distribution the

Dual-frequency ferromagnetic resonance

, 2006
We describe a new experimental technique to investigate coupling effects between different layers or modes in ferromagnetic resonance (FMR). Dual FMR frequencies are excited (2-8 GHz) simultaneously and detected selectively in a broadband RF circuit ...

Shell-ferromagnetism in a Ni-Mn-In off-stoichiometric Heusler studied by ferromagnetic resonance

AIP Advances, 2017
Next to the multifunctional properties of Ni-Mn-based Heusler alloys new functionalities related to shell-ferromagnetism are emerging. To understand in more detail the properties of shell-ferromagnetism we examine a decomposed Ni50.0Mn45.1In4.9 off ...

Voltage Signals Caused by Surface Acoustic Wave Driven Ferromagnetic Resonance Under Out‐of‐Plane External Fields

Advanced Materials Interfaces, 2022
Under an external magnetic field, surface acoustic waves (SAWs) propagating onto a ferromagnetic thin film can excite ferromagnetic resonance (FMR). The magnetization precessional motion in resonance pumps spin current into the Rashba interface across an

Spin battery operated by ferromagnetic resonance

, 2002
Precessing ferromagnets are predicted to inject a spin current into adjacent conductors via Ohmic contacts, irrespective of a conductance mismatch with, for example, doped semiconductors.
