Investigation of High-Temperature Superconducting Trapped Field Magnets in a Superconducting Motor
… research presents a systematic investigation of magnetisation and cross-field demagnetisation in high-temperature superconducting (HTS) trapped field stacks (TFSs) within a partially superconducting machine, employing a finite element method (FEM)-based modelling approach. The key innovations …

Stacks of high temperature superconducting tape as trapped field magnets for energy applications
… materials. In particular, trapped field superconducting magnets, where the field is generated by a circulating persistent current in the sample, can create magnetic fields an order of magnitude higher than possible using conventional ferromagnets, thus increasing the power density …

Development of a Bulk Superconducting Magnet for Benchtop Nuclear Magnetic Resonance
… for the generation of the strong polarising fields required for nuclear magnetic resonance (NMR) when utilised as trapped field magnets (TFMs). To date, these stacks have been magnetised by the quasi-static field cooled magnetisation (FCM) technique within NMR-grade fields, requiring access …

Applications of Pulse-Magnetised Bulk Superconductors
Magnetic fields are used in a wide variety of scientific disciplines, especially those concerned with the macroscopic and microscopic examination of matter. Superconductors have proved to be the most economical form of generating magnetic fields when strong magnetic fields are required. In recent …

Modelling and experimental studies of the magnetic properties of bulk high temperature superconductors
… modelling framework can simulate the various magnetisation processes of bulk HTS in an attempt to understand the generation of relatively large magnetic fields by these materials for their potential use in a number of high field, 'quasi-permanent' magnet applications. Chapters I and 2 …

Advanced Numerical Modelling of Bulk Superconductor Magnetisation
… of a material, and the expulsion of magnetic fields from within its volume, below a certain (critical) temperature. Superconductors can be subdivided into two classifications; type-I, or type-II, with the latter exhibiting a ‘mixed-state’ of superconductivity across their volume. Through …

Magnetisierungsmessungen in hohen magnetischen Impulsfeldern
In der vorliegenden Arbeit wurden vor allem das Auftreten und der Mechanismus von feldinduzierten Übergängen und der damit verbundenen kritischen Felder untersucht. Die verwendete Magnetisierungsmessmethode ist auf die bestehende Impulsfeldanlage des IFW Dresden abgestimmt. Die Magnetisierung in …
