  1. Postgraduate Seminar Series (a) Low carbon mild steel (b) Aluminium Simulation of magnetic field intensity produced by the electromagnet on different samples, showing contours of magnetic field strength. The postgraduate seminar series is a series of informal talks run by postgraduates for postgraduates. All postgraduates are welcome and refreshments are always provided! Thursday 23rd October Room 564 5pm EMATS for high temperature By Jose Francisco Hernandez-Valle In recent years, the demand for novel ultrasonic generation and detection devices to tackle high temperature inspection problems has increased. The methods currently used are usually expensive and highly dependent on surface condition. Electromagnet based EMATs are an alternative approach to the challenge. Presented in this talk; a brief introduction, basic theory review, and experimental work carried out so far. Multiferroics By Dan O’Flynn Multiferroic materials show a coupling between magnetism and ferroelectricity, making them very appealing from both a physical and a technological point of view. Single crystals of well known multiferroics TbMnO3 and DyMnO3 have been grown at Warwick, and their magnetoelectric/physical properties have been measured down to 2K in magnetic fields up to 9T. A new multiferroic system, Sm1-xYxMnO3 has been discovered by our group in recent weeks. Also this week: Pizza!
