High temperature supraconductors

U radu su obrađeni visokotemperaturni supravodiči i njihova današnja primjena. Visokotemperaturnim supravodičima (HTSC) električni otpor naglo pada točno na nulu kada se ohlade na ili ispod temperature koja se naziva kritična temperatura. Supravodljivost je 1911. Godine. otkrio nizozemski fizičar Heike Kamerlingh Onnes. Supravodiči se prema ponašanju u magnetskom polju klasificiraju na TIP I i TIP II. Postoje također i niskotemperatuni supravodiči kojima je kritična temperatura ispod 30 K. Objašnjene su teorije supravodljivosti, koje nas upućuju u strukturu i principe djelovanja supravodljivih elemenata. Opisana je i tehnološka primjena supravodiča koja se svakodnevno koristi u medicini, znanosti i energetici.The paper deals with high-temperature superconductors and their current application. High-temperature superconductors (HTSC) have electrical resistance that drops to exactly zero when cooled to or below a temperature called the critical temperature. Superconductivity is 1911. discovered by Dutch physicist Heike Kamerlingh Onnes. Superconductors are classified according to their behavior in a magnetic field into TYPE I and TYPE II. There are also low- temperature superconductors whose critical temperature is below 30 K. Superconductivity theories are explained, which guide us to the structure and principles of operation of superconducting elements. The technological application of superconductors, which is used every day in medicine, science and energy, is also described
