It was discovered in 1911 by the Dutch physicist Kamerlingh Onnes, a phenomenon in which electrical
resistance rapidly reaches zero at any temperature when the temperature of any kind of metal, alloy, or
compound is lowered.
Currently, superconductivity has been confirmed in more than 1,000 materials such as metal elements,
alloys, metal compounds, organic matter, and oxides, and the critical temperature ranges from 0.01K to
room temperature.
Superconductivity is expected to have a wide range of applications, including power systems for sexual
energy, nuclear fusion and MHD power generation, superconducting magnets used in magnetic levitation
trains, devices using the Josephson effect, and sensors. Conventional superconducting materials could
only be used near cryogenic temperatures, so there were many problems with cooling in practical terms.
However, with the recent development of oxide superconductors, room temperature superconductivity
has been realized, and a huge market is expected to be formed in the future.
HANA experiences with SQUID(Superconducting QUantum Interference Device) sensor and LTS/HTS
magnets.
HANA also manufactures customized cryostats for Superconductivity and Quantum computer application.
