초록: To analyze the nature of electronic interactions, it is necessary to study order parameters such as spin alignment, charge distribution, lattice symmetry, and orbital ordering. Experimentally, by switching the external conditions, drastic changes in the order parameters can be detected. My research is concentrated to the effect on the complex coupling between order parameters which is so-called strongly correlated system.

In this seminar, the first part will be presented of electronic properties in solids. Especially in metallic system, the shape of FS can be understood by means of Quantum oscillations and angle-dependent magnetoresistance oscillations (AMROs) by applying high magnetic fields. Also recently observed new bulk Dirac system will be presented.
Then, there are several methods to understand magnetic properties in solids. Among them, I’d like to emphasize the torque measurement. In multiferroic system, when the high magnetic field drastically changes the magnetic ordering, magnetoelectric properties also changes.
