Manuscript Topics
The magnetic properties of magnetic materials, such as coercive fields or saturation magnetization, are essential for their possible applications. Besides pure magnetization curves, it may be interesting to measure magnetic properties of samples under electrical or mechanical influence. Several techniques, based on different physical effects, can be used for this purpose. Amongst them, typical measurements are based on force techniques, fluxmetric, magnetometric, magneto-optical, magnetostrictive techniques or magnetic resonance methods [1]. The optimal measurement methods depend on several sample properties, such as the type of magnetism, sample size and surface roughness. Besides, external parameters, such as temperature or mechanical stress, can influence the measurement results, and static and dynamic measurements may reveal different properties of the specimens under investigation.
With recent developments in magnetic and spintronics devices, researchers experience new challenges in measurements of magnetic properties, e.g. due to smaller and smaller nanostructures, ultrafast magnetization reversal processes, 3D printed magnetic samples with unusual anisotropies, etc. This special issue covers recent techniques to measure magnetic properties as well as well-known techniques, performed on uncommon specimens. Experimental and review manuscripts dealing with the following topics are highly welcome:
- Ultrafast magnetization reversal
- Temperature assisted magnetization dynamics
- Scattering and diffractive methods for magnetic materials evaluations
- Magneto-optical measurements on rough surfaces
- Diffracted magneto-optical Kerr effect (DMOKE) on nanostructure arrays
- Measurements at high external magnetic fields
- Measuring with highest magnetization resolution
- Detecting geomagnetic properties
- First-order reversal curve (FORC) diagrams and their evaluation
- Limitations of magnetization measurement techniques and approaches to overcome them
