Extreme anti-reflection enhanced magneto-optic Kerr effect microscopy [PDF]
Nature Communications, 2020 Magneto-optic Kerr effect microscopy is useful for dynamic magnetic studies, but is limited by the weak magneto-optical activity. Here, the authors show that extreme anti-reflection result in a Kerr amplitude as large as 20° and enables real-time ...

Direct Experimental Demonstration of Bend-Induced Transformation of Magnetic Structure in Amorphous Microwires [PDF]
SensorsIn the pursuit of active elements for bending and curvature sensors, magneto-optical investigations were performed on bent microwires. For the first time, local surface magnetization reversal curves were obtained from various sides of bent Co-rich and Fe-

Spiral Annealing of Magnetic Microwires [PDF]
SensorsA preprocessing technique named “spiral annealing” was applied for the first time to magnetic microwires. In this process, the sample was arranged in a flat spiral shape during annealing, and subsequent measurements were conducted on the unbent sample ...

Disentangling the magneto-optic Kerr effect of manganite epitaxial heterostructures
AIP Advances, 2023 The magneto-optic Kerr effect can probe the process of magnetization reversal in ferromagnetic thin films and can, thus, be used as an alternative to magnetometry.

Features of the low-temperature transformation in the micromagnetic structure of the intermetallic compound Ho2Fe17 [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2018 We found that a three-phase micromagnetic structure may emerge when a magnetic field is applied to the intermetallic compound Ho2Fe17 with the magnetic crystallographic anisotropy of the «easy plane» type in the temperature range 10 ÷ 110 К.
