Superconductors are materials that exhibit zero electrical resistance when cooled below a critical temperature. This extraordinary phenomenon allows superconductors to conduct electricity without any energy loss, making them highly attractive for various technological applications. The discovery of superconductivity dates back to 1911 when the Dutch physicist Heike Kamerlingh Onnes first observed it in mercury cooled to very low temperatures. Since then, extensive research has been conducted to understand and harness the unique properties of superconductors for practical use.
One of the defining characteristics of superconductors is the Meissner effect, where they expel magnetic fields from their interior upon entering the superconducting state. This behavior enables superconductors to levitate magnets and maintain stable currents without any dissipation. Additionally, superconductors can carry much higher current densities compared to conventional conductors, paving the way for highly efficient electrical transmission systems and powerful electromagnets. These properties have propelled superconductors into the field of cutting-edge technologies with immense potential for revolutionizing various industries.
In 1911, Dutch physicist Heike Kamerlingh Onnes made a groundbreaking discovery when he successfully liquefied helium to near absolute zero temperatures. This achievement led to the observation of superconductivity in mercury, where its electrical resistance dropped to zero as it was cooled to temperatures below a critical point. This momentous breakthrough marked the birth of superconductivity as a field of study and opened the door to a plethora of research and technological advancements in the years to follow.
Following on from Kamerlingh Onnes's work, the discovery of Type I superconductors like lead and tin in the 20th century revolutionized the scientific community's understanding of materials exhibiting zero electrical resistance. These early superconductors helped lay the foundation for further exploration into the phenomenon, eventually leading to the emergence of more complex and versatile Type II superconductors. The historical journey of superconductors is a testament to the collaborative efforts of scientists and engineers worldwide, all striving to unlock the full potential and applications of these remarkable materials in various industries and technologies.
There are two main categories of superconductors: conventional superconductors and high-temperature superconductors. Conventional superconductors are typically metallic elements or simple alloys that exhibit superconducting properties at very low temperatures, close to absolute zero. These materials follow the BCS theory of superconductivity, which explains superconductivity as a result of electron pairs forming with opposite spins and momentum. On the other hand, high-temperature superconductors were discovered more recently and can exhibit superconducting behavior at temperatures higher than traditional superconductors, although still below room temperature. These materials are typically complex compounds containing copper and oxygen, known as cuprates, or iron-based superconductors. Their mechanism of superconductivity is not yet fully understood, making them an exciting area of research in the field.
Low-temperature superconductors exhibit remarkable properties that distinguish them from conventional materials. One of the defining features of low-temperature superconductors is their ability to conduct electricity with zero resistance when cooled below a critical temperature. This phenomenon, known as superconductivity, allows for the efficient transfer of electrical currents without any energy loss, making these materials highly coveted for various technological applications.
Furthermore, low-temperature superconductors possess a unique property called the Meissner effect, which expels magnetic fields from their interior. This expulsion of magnetic fields enables low-temperature superconductors to maintain perfect diamagnetism, a characteristic that finds utility in applications such as magnetic levitation and magnetic resonance imaging (MRI) systems. The combination of zero electrical resistance and the Meissner effect underscores the exceptional properties of low-temperature superconductors and underscores their critical role in advancing numerous technological innovations.
The unique properties of low-temperature superconductors have sparked interest in various practical applications across different industries.

This advantage opens up new possibilities for advancements in technology and scientific research that rely on precise magnetic fields for their operations.
One drawback of low-temperature superconductors is the requirement for extremely low temperatures to maintain their superconducting state. This necessitates the use of expensive cryogenic systems to cool the materials to temperatures close to absolute zero, which can be costly and energy-intensive. The need for these specialized cooling systems adds complexity to the design and operation of superconducting devices, limiting their practicality in certain applications.
Additionally, the brittleness of low-temperature superconductors poses a challenge in their fabrication and usage.
