Curietemperatuuri

Curietemperature, also known as Curie point, is the temperature at which a ferromagnetic material becomes paramagnetic. This transition occurs due to the alignment of magnetic domains within the material. Below the Curie temperature, the material exhibits strong magnetic properties, while above this temperature, the magnetic domains lose their alignment, and the material becomes weakly magnetic or paramagnetic.

The Curie temperature is named after Pierre Curie, a French physicist who first observed this phenomenon. It is a critical parameter in the study of ferromagnetic materials and is used to characterize their magnetic properties. The Curie temperature varies depending on the material; for example, iron has a Curie temperature of approximately 770 degrees Celsius, while cobalt has a higher Curie temperature of about 1,115 degrees Celsius.

The Curie temperature is influenced by several factors, including the material's composition, crystal structure, and the presence of impurities. Understanding the Curie temperature is essential in various applications, such as magnetic data storage, magnetic sensors, and magnetic refrigeration. Researchers continue to study the Curie temperature to develop new materials with tailored magnetic properties for advanced technological applications.
