SUPERDIAMAGNETISM Meaning and
Definition
-
Superdiamagnetism refers to an extraordinary type of diamagnetic behavior observed in certain materials when subjected to a magnetic field. Diamagnetism is a phenomenon where materials have a weak tendency to become magnetized in the opposite direction to an applied magnetic field, leading to a repulsive force. In the context of superdiamagnetism, materials exhibit an unusually strong diamagnetic response, going beyond the typical response observed in ordinary diamagnetic materials.
The term "superdiamagnetism" is commonly used to describe materials at extremely low temperatures, particularly when they are close to their absolute zero. At these temperatures, certain materials, usually metals or alloys, can display a significant increase in their diamagnetic properties, leading to a stronger repulsion against a magnetic field. This enhanced diamagnetic response arises from the phenomenon of electrical resistance approaching zero under exceptional cooling conditions.
Superdiamagnetism is of particular interest in various scientific and technological applications. It has been extensively studied and utilized in the field of superconductivity, as the peculiar magnetic properties exhibited by superdiamagnetic materials can provide valuable insights and aid in the development of more effective superconducting materials. Additionally, superdiamagnetism has potential applications in magnetic levitation, where it can be harnessed to suspend objects in mid-air using the repulsive force generated in the presence of a magnetic field.
In summary, superdiamagnetism describes the remarkable increase in the diamagnetic properties of certain materials at extremely low temperatures, leading to a heightened repulsive force against a magnetic field.
Etymology of SUPERDIAMAGNETISM
The word "superdiamagnetism" is derived from a combination of two components:
1. "Super": It comes from the Latin prefix "super-" meaning "above" or "beyond". In English, this prefix is often used to intensify or enhance the meaning of the word it is attached to.
2. "Diamagnetism": It is a scientific term that refers to the property of certain materials to develop a weak magnetic field in opposition to an externally applied magnetic field. The term "diamagnetism" incorporates the prefix "dia-" which means "through" or "across" in Greek but is used here in the sense of "opposite" or "against".
Therefore, "superdiamagnetism" is a term that implies a stronger or enhanced form of diamagnetism, indicating a significant opposition to an external magnetic field.
