Abstract Soybean is an emerging strategic crop for nutrition, food security, and livestock feed in Africa, but improvement of its productivity is hampered by low genetic diversity. There is need for broadening the tropical germplasm base through inco

The presented research is devoted to the construction and calculations of the density model along the regional CMRV-DSS profile RP-17 (Chop–Velykyy Bychkiv), running along the Transcarpathian depression. Based on the results of density modeling, th

We studied vortex nucleation/annihilation process and its temperature dependence in micromagnetic objects with lowered symmetry using micro-Hall magnetometry. Magnetization reversal curves were obtained for the Pacman-like nanodots placed directly on

We report on broadband ferromagnetic resonance studies of [ Pt tPt / Co tCo / Pt tPt ]N multilayer thin films, using a flip-chip method with a high frequency coplanar waveguide at room temperature. We investigate the dependence of the magnetic parame

We demonstrated numerically the skyrmion formation in ultrathin nanodisks using a magnetic force microscopy tip. We found that the local magnetic field generated by the magnetic tip significantly affects the magnetization state of the nanodisks and l

We have designed and implemented a dual-cantilever magnetometer, in which the coupling magnetic forces between the two cantilevers can be switched on/off by an external magnetic field. The coupling is realized by a pair of ferromagnetic ellipses, loc

We have developed a vortex-core magnetic force microscope (VC MFM) for magnetic field imaging at the nanoscale for many research fields—physics, biology, materials science, and metrology. The method solves principally quantitative scanning by incre

Self-aligned normally-off n(++)GaN/InAlN/AlN/GaN MOS HEMTs with a recessed gate show scalable threshold voltage between 1.3 to 3.7V, which increases with the gate oxide thickness. Al2O3 or HfO2 gate insulators were grown by ALD at 100 degrees C so th

We prepared Pt/HfO 2 /TiN metal–insulator–metal structures for resistive switching experiments. The HfO 2 films were prepared by thermal, ozone and plasma assisted atomic layer deposition. The deposition techniques yielded HfO 2 films that were c

In this work we systematically study the effect of the Al 2 O 3 barrier layer thickness on the resistive switching properties of Al 2 O 3 /TiO 2 bilayer grown by atomic layer deposition in the Pt/Al 2 O 3 /TiO 2 /TiN stacks. It was found that an Al 2
