Magnetism and superconductivity

The research in the group of Magnetism and superconductors concentrates mainly on magnetic perovskite materials and high temperature superconductors. Both classes have emerging properties due to high electron-electron correlations, which makes them very interesting, but also difficult to thoroughly understand and model. Examples of such properties are high temperature superconductivity and colossal magnetoresistivity. The future of superconductors looks promising as they provide better energy efficiency for very many high power applications. Magnetoresistive materials, on the other hand, enable spintronics, where the electron spin is used in addition to the charge, as in normal electronics.

We typically make all our thin film samples ourselves, either using pulsed laser deposition (PLD) or e-beam evaporation. The samples are then characterized by structurally, magnetically and electrically. For these, we have good experimental facilities in house: x-ray diffractometer (XRD), scanning electron microscope (SEM) and atomic force microscope (AFM). Magnetic properties can be studied with  SQUID-magnetometer or AC-magnetometer. Transport properties, we study mainly in the Physical Property Measurement System (PPMS) with 9 T magnet and self-made option to go up to TΩ range in resistivity.

The group leader is professor Petriina Paturi. You can find all our publications in the links from the personnel page.
