- Research interests
Nicola Morley's research centres on functional magnetic materials, including the understanding and development of magnetic films to be used in magnetic devices and sensors. The main research areas are:
Fe-based Magnetostrictive Materials and Devices
Research is focused on the fabrication and characterisation of Fe-based magnetostrictive film, including Fe-Co and Fe-Ga for MEMS device applications. Fabrication techniques include a state of the art co-sputter-evaporation deposition system, RF/DC sputter system and an evaporator. A wide range of characterisation techniques are used, which include XRD, AFM/MFM, MOKE magnetometry and resistance measurements, as well as central facilities (ESRF, France, diamond, UK). The main aim of the work is to understand the relationship between the magnetostriction, microstructure and magnetisation. The work has also involved the development of magnetostrictive MEMS devices, which includes magnetostrictive actuators for structural health monitoring, magnetostrictive energy harvesters and mass MEMS sensors.
This research investigates the spin transport within organic semiconductors, including the development of room temperature organic spin-valves. The spin transport has been investigated using a range of techniques including magnetoresistance, XPS, MOKE magnetometry, AFM and muon spectroscopy. The main aims are to understand how the interfaces influence the spin transport in organic spin-valves and develop novel organic spin devices, such as the spin switch. Research has studied both lateral and vertical devices at room temperature.
This research involves studying multilayer multiferroics to investigate how the optical, electrical and magnetic properties are linked within the hetrostructures. Work has studied how the interfaces influence the overall properties of the structures. Characterisation techniques include XRD, SEM, TEM, AFM/MFM, MOKE magnetometry and electrical measurements.
Functional Magnetic Materials
This research involves investigating functional magnetic materials (magnetocaloric, soft and hard magnets and magnetostrictive) using novel techniques such as spark plasma sintering (SPS), additive layer manufacture (ALM) and thin films, to determine how the structural properties of the materials influence the functional properties. The work has included studying element substitution, high entropy alloy and materials design using computational methods.
