Steven has successfully defended his PhD thesis entitled “Anisotropic Behaviour of Magneto-electric Coupling in Multi-ferroic Composites” and will be awarded his degree subject to minor corrections. It will be nice to see his thesis added to the shelf of the Group’s Alumni. Well done ‘Dr’ Bourn.
The 62nd annual conference on Magnetism and Magnetic Materials is well underway in downtown Pittsburgh. On Tuesday, Dr. Tim Mercer presented some of the group’s latest work in a contributed talk in the ‘Strain-Mediated Multiferroic Hetrostructures’ morning session, AH:
We recently presented our work at the 61st Annual Conference on Magnetism and Magnetic Materials in New Orleans LA. Dr. Tim Mercer is shown here at the Wednesday poster session discussing our findings on “Mesoporous Nanoparticle Supported Liposomes for Magnetic Hyperthermia Triggered Drug Delivery”
Pulsed domain wall movement is studied here in Ni80Fe20 nanowires on SiO2 , using a fully integrated electrostatic, thermoelectric, and micromagnetics solver based on the Landau-Lifshitz-Bloch equation, including Joule heating, anisotropic magneto-resistance, and Oersted field contributions. During the applied pulse, the anisotropic magneto-resistance of the domain wall generates a dynamic heat gradient, which increases the current-driven velocity by up to 15%. Using a temperature-dependent conductivity, significant differences are found between the constant voltage-pulsed and constant current-pulsed domain wall movement: constant voltage pulses are shown to be more efficient at displacing domain walls whilst minimizing the increase in temperature , with the total domain wall displacement achieved over a fixed pulse duration having a maximum with respect to the driving pulse strength.
The Joint European Magnetics Symposia (JEMS) 2016 is in full swing. Glasgow is an interesting city that gives visitors a warm and friendly welcome. On Monday Dr. Serban Lepadatu presented work on the effects of edge and surface roughness in ferromagnetic nanowires (Poster PS.1.082) and on Tuesday Mr. Steven Bourn gave a talk on our multi-ferroic project concerning the effects of anisotropy in the magnetic layer on the Magneto-Coupling effect (Sumposium “Perovskites, multiferroics, artificial/composite multiferroics)
Dr. Serban Lepadatu presents his work at the first poster session
“The Effects of Multiple Anisotropy axes on Magneto-Electric Coupling in Multiferroic Composites”
Yesterday was our slot (AP-03) for the morning presentation of our latest work on multi-ferroic composites. The photo shows Tim Mercer at the end of the session stood by his poster. The poster generated a lot of interest and forms the main part of Steven Bourn’s PhD project.
The 13 Joint MMM-Intermag Conference is in San Diego, CA and is amongst the biggest and most widely accepted forum for bringing together researchers from all over the world to present asnd discuss their research on all aspects of magnetism and magnetic materials
The conference has kicked-off in fine style with the tradiional BierStube (and what a fine tradtion it is).
Tomorrow I will be presenting the work from our Multi-ferroic project (the postgraduate PhD student on this project is Mr Steven Bourn) in the morning poster session. In the meantime, a few images from near the hotel:
