Low-temperature superconducting materials need to operate at liquid helium temperature (4.2K), while high-temperature superconducting materials can achieve superconducting state at liquid nitrogen temperature (77K). The discovery of high-temperature superconducting materials has greatly promoted the application of superconducting technology.
