Depth profile of ferromagnetic layered samples studied with photothermally modulated magnetic resonance
نویسندگان
چکیده
Depth profile analysis of a ferromagnetic layered sample composed of y-Fe203 and Cr02 tapes were performed with photothermally modulated ferromagnetic resonance (PMFMR). Those analysis were done by using phase-resolved and modulation frequency variation methods. The experiments showed the advantages of this technique over the conventional one. The dependency of the detected signal on the modulation frequency was also studied for single layer samples, thus determining the microwave-absorbing layer thickness of the tapes.

Photothermally modulated ferromagnetic resonance investigations of epitaxially grown thin Fe (001) films
The photothermally modulated (PM) ferromagnetic resonance (FMR) combines the high sensitivity of conventional FMR and the spatial resolution of thermal waves. For the first time, this alternative FMR-technique was applied to the magnetic characterization of high-quality thin Fe (001) films epitaxially grown on (001) GaAs substrate: Images of the distribution of crystalline anisotropy constant K...

Grazing Incidence X-Ray Fluorescence (GI-XRF) technique is a powerful tool for the characterization of depth profile concentrations in multilayered samples. A modeling program called ANDEN has been developed for simulating GI-XRF data for layered thin films [1]. ANDEN was used as one of the tools to study the dependence of dopants distribution with magnetic behavior in Diluted Magnetic Semicond...

We have studied the magneto-elastic coupling in the double layered Mn perovskite La1.2Sr1.8Mn2O7 with an ultrasonic velocity technique. The temperature profile of both the in-plane and out-of-plane longitudinal velocities showed a large stiffening anomaly below the insulating paramagnetic to metallic ferromagnetic transition. Magnetic fluctuations effects consistent with the layered structure a...
متن کاملSpin precession mapping at ferromagnetic resonance via nuclear resonant scattering of synchrotron radiation.
We probe the spin dynamics in a thin magnetic film at ferromagnetic resonance by nuclear resonant scattering of synchrotron radiation at the 14.4 keV resonance of ^{57}Fe. The precession of the magnetization leads to an apparent reduction of the magnetic hyperfine field acting at the ^{57}Fe nuclei. The spin dynamics is described in a stochastic relaxation model adapted to the ferromagnetic res...
متن کاملMagnetoelectric interactions in ferromagnetic-piezoelectric layered structures: Phenomena and devices
Layered magnetostrictive-piezoelectric structures are multifunctional due to their dual-responsiveness to mechanical and electromagnetic forces. Here, we discuss studies of magnetoelectric (ME) interactions in ferrite-lead zirconate titanate (PZT) and terfenol-PZT material couples. Key findings include: (1) the observation of a giant lowfrequency ME effect in the layered systems; (2) data analy...
