Development of Magnetic Microwires for Magnetic Sensor Applications
(MDPI, 2019-11-02)
Thin magnetic wires can present excellent soft magnetic properties (with coercivities up to 4 A/m), Giant Magneto-impedance effect, GMI, or rectangular hysteresis loops combined with quite fast domain wall, DW, propagation. ...
Optimization of magnetic properties and GMI effect of Thin Co-rich Microwires for GMI Microsensors
(MDPI, 2020-03-11)
Magnetic microwires can present excellent soft magnetic properties and a giant magnetoimpedance effect. In this paper, we present our last results on the effect of postprocessing allowing optimization of the magnetoimpedance ...
Engineering of Magnetic Softness and Domain Wall Dynamics of Fe-rich Amorphous Microwires by Stress- induced Magnetic Anisotropy
(Nature Publishing, 2019-08-27)
We observed a remarkable improvement of domain wall (DW) mobility, DW velocity, giant magnetoimpedance (GMI) effect and magnetic softening at appropriate stress-annealing conditions. Beneficial effect of stress-annealing ...
Impact of Stress Annealing on the Magnetization Process of Amorphous and Nanocrystalline Co-Based Microwires
(MDPI, 2019-08)
The domain wall (DW) dynamics of amorphous and nanocrystalline Co-based glass-coated microwires are explored under the influence of stress annealing. Different annealing profiles have enabled remarkable changes in coercivity ...
Review of Domain Wall Dynamics Engineering in Magnetic Microwires
(MDPI, 2020-12-01)
The influence of magnetic anisotropy, post-processing conditions, and defects on the domain wall (DW) dynamics of amorphous and nanocrystalline Fe-, Ni-, and Co-rich microwires with spontaneous and annealing-induced magnetic ...
Design and validation of an open-source modular Microplate Photoirradiation System for high-throughput photobiology experiments
(Public Library Science, 2018-10-05)
Research in photobiology is currently limited by a lack of devices capable of delivering precise and tunable irradiation to cells in a high-throughput format. This limits researchers to using expensive commercially available ...
Non-Linear Optical Properties of Er3+–Yb3+-Doped NaGdF4 Nanostructured Glass–Ceramics
(MDPI, 2020-07-21)
Transparent oxyfluoride glass–ceramics containing NaGdF4 nanocrystals were prepared by melt-quenching and doped with Er3+ (0.5 mol%) and different amounts of Yb3+ (0–2 mol%). The selected dopant concentration the crystallization ...
Transparent Sol-Gel Oxyfluoride Glass-Ceramics with High Crystalline Fraction and Study of RE Incorporation
(MDPI, 2019-04-03)
Transparent oxyfluoride glass-ceramic films and self-supported layers with composition 80SiO₂-20LaF₃ doped with Er3+ have been successfully synthesized by sol-gel process for the first time. Crack-free films and self-supported ...
A New Sol-Gel Route Towards Nd3+-doped SiO2-LaF3 Glass-Ceramics for Photonic Applications
(Royal Society Of Chemistry, 2020-12-01)
Glass-ceramic materials with composition 0.9Nd(3+)-80SiO(2)-20LaF(3) were successfully obtained and further heat-treated at 450 degrees C for 6 h. Stable and homogeneous LaF3 nanoparticle suspensions with and without Nd3+ ...
Energy Test of an Efficient Random Laser Emission Collecting System
(SPIE-Society of Photo-Optical Instrumentation Engineers, 2021-01-29)
The problem of light collection in random lasers (RLs) is addressed. As the radiation emitted by this system is Lambertian due to its spatial incoherence, a device based on an ellipsoidal revolution mirror is designed, ...
