Magnetic Force Microscopy and Micromagnetic Simulations of Nanoscale Magnetic Structures and Modified Artificial Spin Ices
(Master thesis, 2020)Kunstige spinnis betegner magnetiske metamaterialer som består av koblede nanomagneter plassert i et gitter. De utgjør interessante system fordi de gir mulighet til å skreddersy magnetiske egenskaper. Videre har de et ... -
Magnetic Force Microscopy of Magnetic Nanodisk Arrays at Room Temperature
(Master thesis, 2019)De senere årene har verden opplevd en eksponentiell økning i energiforbruket relatert til informasjonsteknologi og data. Samtidig er det et intenst behov for å redusere verdenssamfunnets samlede energiforbruk. Dette gjør ... -
Magnetic Forces and Vibration in Wind Power Generators: Analysis of Fractional-Slot Low-Speed PM Machines with Concentrated Windings
(Doctoral thesis at NTNU;2015:204, Doctoral thesis, 2015)The PhD research work presented in this thesis deals with radial magnetics forces and vibration in low-speed fractional-slot permanent magnet (PM) machines with concentrated windings. One of the applications of such ... -
Magnetic geophysical mapping of prehistoric iron production sites in central Norway
(Chapter, 2019)The slag pit furnace of the Trøndelag tradition for iron production is a very specific cultural-historical tradition in central Norway in the Early Iron Age, but few of these iron production sites have been excavated in ... -
Magnetic Lenz lenses improve the limit-of-detection in nuclear magnetic resonance
(Peer reviewed; Journal article, 2017)A high NMR detection sensitivity is indispensable when dealing with mass and volume-limited samples, or whenever a high spatial resolution is required. The use of miniaturised RF coils is a proven way to increase sensitivity, ... -
Magnetic levitation system: Design, prototyping and testing of a digital PID-controller
(Bachelor thesis, 2022)Denne bacheloroppgaven handler om design, utvikling og bygging av en magnetisk levitasjonsplattform samt posisjonsregulering av en leviterende magnet ved hjelp av en digital PID-regulator. For å oppnå dette har en matematisk ... -
