Superconducting magnets have been extensively used in biomedical fields. They include MRI in diagnostics and NMR spectroscopy for the research of molecular structures. As higher magnetic field levels with small sizes are desirable characteristics of these kinds of devices, to achieve stronger and compacter superconducting magnets is one of our group’s major interests. A new era of physics has come since superconducting technology enabled constructing tremendous size of magnets. Fusion magnets for next generation energy by accelerating particles for experimental purposes to reveal fundamental structure of the particles are the main examples. Our group expects that the use of High Temperature Superconductor (HTS) will revolutionize physics development via superconducting devices with compactness and better performance. Recently, power utilities have also begun to use superconductor-based transformers and fault limiters. This new generation of HTS superconducting fault limiters is being called upon due to their ability to respond in just thousandths of a second to limit tens of thousands of amperes of current. A quantum computer leverages quantum mechanical phenomena to manipulate information. To realize a quantum computer, superconductivity is the most important issue to create and maintain a quantum state. Quantum computers are typically designed in the radio-frequency spectrum, cooled down in dilution refrigerators below 100mK with superconductors. To maintain qubits as long as possible, superconducting microwave resonators with high Q-factors are now one of the most important research goals.
