170 & 182 Dennison Building
Speaker: Dr. Sa-Lin Cheng Bernstein (U-M Physics)The phenomenon of superconductivity is characterized by the absence of electrical resistivity below a critical temperature, T_c, and the physical property of perfect diamagnetism - the expulsion of magnetic fields - below a critical magnetic field, H_c. Superconductivity occurs only in select materials of two types: I and II. The recently discovered high-T_c superconductors are all of Type II. Dr. Sa-Lin Cheng Bernstein will explain how Type II superconductors afford greater potential for practical applications in the real world, such as power transmission, superconducting magnets in generators, and energy storage devices.
All talks are free and refreshments will be served. Visitor parking for the seminars (Central Campus) is across the street from the Dennison Building in the U-M Church Street structure. There is a $2.00 parking charge implemented by U-M Parking Services.
