Title: Magnetism on the Verge of Breakdown
Speaker: Dr. May Chiao

Magnetism, particularly the kind found in iron, is usually considered to be very stable. However, a plethora of recent work has shown that magnetic interactions can be continuously weakened by the application of external pressure. Then other interactions can be made dominant and surprising phases can exist, such as exotic forms of superconductivity. I will present an overview of this quantum wild west, and look closely at one particular model system, Sr3Ru2O7, whose interactions can be tuned by both magnetic field and angle.
