LK-01 - PhD position: Synthesis and Investigations of Multiferroic Thin Film Materials

Contract Type: Full Time/Fixed Term

Tyndall National Institute at University College Cork invites applications for a PhD position. The project will involve the synthesis and characterisation of thin film materials with electronic and magnetic properties (multiferroic materials) for potential data/memory storage applications. This stimulating PhD studentship is part of Dr. Keeney’s prestigious Royal Society-Science Foundation Ireland University Research Fellowship.

Multiferroic materials, possessing simultaneous electric and magnetic memory states, have been road-mapped as promising multi-state architectures for memory scaling beyond current technologies. No such devices currently exist however, as multiferroic materials with room temperature properties are extremely rare. Therefore the design and development of a room temperature multiferroic material was a significant output of our recent research. We are therefore eager to exploit this material and to address the intriguing research questions that this tantalising material opens up. While all samples synthesised demonstrate magnetic behaviour, a variation in magnetic response is observed. To produce samples with optimised and reliable magnetic response and to exploit this material for future data storage technologies, it is necessary to understand the origin of the room temperature magnetisation. Our latest work demonstrates that the magnetic ions tend to congregate to the centre of the structure, aligning close to each other which would permit them to interact and create pathways for long-range magnetic order.

Thus, in this project a systematic study will be performed whereby samples are synthesised to tailor their orientation and extent of magnetic ion partitioning. This will be correlated with the magnetic responses measured to ascertain the optimum conditions for magnetism and enhance the properties of this multiferroic material for potential future memory storage applications.

Responsibilities

The project aims to correlate the magnetic and magnetoelectric properties of room temperature multiferroic materials with their crystallite orientation and sub-unit cell characteristics.  The PhD student will focus on fabrication of layered-structured Aurivillius phase thin films on suitable substrates by chemical solution deposition, and liquid injection chemical vapour deposition (LI-CVD) techniques. This will enable subsequent investigations of the micro-structural characteristics, magnetic properties and magnetoelectric coupling mechanisms by the student as a function of fabrication technique and substrate type/orientation. X-ray diffraction analysis of their structural properties will be key to the investigations along with piezoresponse force microscopy investigations of their electrical, magnetic and magnteoelectric properties. Collaboration with internal and external researchers will be an important part of the project as well as disseminating results in peer-reviewed publications and at national and international conferences.
