SmCo-based MFM probes with high switching fields
نویسندگان
چکیده
MFM probes with high switching fields have been synthesized by depositing Cr/SmCo5/Cr trilayers onto commercial Si AFM probes. The maximum field values of the (between 4 T and 5 for annealed at 550 °C min) is lower than coercivity measured on similar (6.8 T) deposited a substrate. Reducing annealing time results in while increasing leads to drop magnetization Such ultra-high are interest characterizing range materials including hard magnetic remanent state or under an external applied transducers excitation.

Customized MFM probes with high lateral resolution
Magnetic force microscopy (MFM) is a widely used technique for magnetic imaging. Besides its advantages such as the high spatial resolution and the easy use in the characterization of relevant applied materials, the main handicaps of the technique are the lack of control over the tip stray field and poor lateral resolution when working under standard conditions. In this work, we present a conve...
متن کاملHigh-contrast Cu(I)-selective fluorescent probes based on synergistic electronic and conformational switching.
The design of fluorescent probes for the detection of redox-active transition metals such as Cu(I/II) is challenging due to potentially interfering metal-induced non-radiative deactivation pathways. By using a ligand architecture with a built-in conformational switch that maximizes the change in donor potential upon metal binding and an electronically decoupled tunable pyrazoline fluorophore as...
متن کاملSwitching fields
Most scientists would probably agree that switching fields from time to time is a good thing — for both scientist and science. MacFarlane Burnett and Neils Jerne, for example, each brought concepts and technology from microbiology to immunology, and, as a consequence, the clonal selection hypothesis, which revolutionized immunology, was born. Why then is field-switching not more common? One rea...
متن کامل[DNA duplex-based fluorescence probes/sensors using monomer-excimer switching].
In this review, we report DNA duplex-based fluorescence probes/sensors using pyrene monomer-excimer switching. The review mainly comprises two topics: 1) excimer-monomer switching molecular beacons (EMS-MB) and 2) monomer-excimer switching sensors based on the structural motif of antibodies. The EMS-MBs have two pyrene fluorophores connected both at 3' and 5' ends of a single-stranded oligonucl...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
