Episode 6: Superconductor robust against magnetic field

MRS Bulletin Materials News Podcast

In this podcast episode, MRS Bulletin’s Sophia Chen interviews Kaveh Ahadi from The Ohio State University about a material his group developed that maintains superconductivity in a magnetic field. The researchers grew a film of lanthanum manganite on a crystal of potassium tantalate. When lowered to the temperature of 2 Kelvin, the material is a superconductor. When Ahadi’s group applied 25 Teslas of magnetic field, the material stayed superconducting. Even though the material is not of practical use, Ahadi says that studying this material will help researchers better understand the mechanisms that lead to superconductivity. This work was published in Nano Letters.
