Magnetic control of superconducting heterostructures using compensated antiferromagnets
(Peer reviewed; Journal article, 2021)Due to the lack of a net magnetization both at the interface and in the bulk, antiferromagnets with compensated interfaces may appear incapable of influencing the phase transition in an adjacent superconductor via the spin ... -
Magnetic Design for High Temperature, High Frequency SiC Power Electronics
(Master thesis, 2013)Power electronic components which can operate at high temperatures would benefit a large number of different applications such as in petroleum exploration, aviation and electrical vehicles. Silicon carbide semiconductors ... -
Magnetic domain configuration of (111)-oriented LaFeO3 epitaxial thin films
(Journal article; Peer reviewed, 2017)In antiferromagnetic spintronics control of the domains and corresponding spin axis orientation is crucial for devices. Here we investigate the antiferromagnetic axis in (111)-oriented LaFeO3/SrTiO3, which is coupled to ... -
Magnetic domain formation in ultrathin complex oxide ferromagnetic/antiferromagnetic bilayers
(Journal article; Peer reviewed, 2018)In this study, we report on the magnetic domain formation in ultrathin blanket films and patterned micro- and nanostructures of ferromagnetic (FM) La0.7Sr0.3MnO3 single-layers and antiferromagnetic (AF)/ferromagnetic ... -
Magnetic field compensation coil design for magnetoencephalography
(Peer reviewed; Journal article, 2021)Acknowledgements This project was supported by the Max Planck Society; and the Free State of Thuringia under 2018 IZN 004 cofinanced by the European Union under the European Regional Development Fund (ERDF); CFD’s research ... -
Magnetic Field Energy Harvesting in Railway
(Peer reviewed; Journal article, 2022)Magnetic field energy harvesting (MFEH) is a method by which a system can harness an ambient, alternating magnetic field in order to scavenge energy. Presented in this article is a novel application of the concept aimed ... -
Magnetic field norm SLAM using Gaussian process regression in foot-mounted sensors
(Chapter, 2021)We propose an application of magnetic field norm simultaneous localisation and mapping to measurements from a foot-mounted sensor for pedestrian navigation. The algorithm is, to the best of the authors’ knowledge, the first ... -
Magnetic field-mappings in low field large-aperture accelerator magnets
(Bachelor thesis, 2023)Roterende-spole målinger er en av de mest brukte metodene for målinger av partikkelakselerator- magneter, fordi den har høy nok presisjon og robusthet. En av begrensingene til målemetoden er at den gir lav fleksibilitet, ... -
Magnetic flux density measurements and mobile phone provocation studies: Investigations in the 50 Hz and the mobile phone frequency regions
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:114, Doctoral thesis, 2007)The aims of this thesis work were divided into two main areas. The first area was an investigation of the extremely low frequency magnetic fields in urban environment and from electrical devices. The second area was mobile ... -
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, ... -
