Why the crystalline defects are called thermodynamic defects?
Asked by | 08 Apr, 2012, 03:11: PM
answered-by-expert Expert Answer
At times these defects are called thermodynamic defects because the number of these defects depend on the temperature.
 
All magnetically ordered solids, ferromagnetic and anti-ferromagnetic solids change into paramagnetic at high temperature.This is because of randomization of domains on heating. Each ferromagnetic substance has a characteristic temperature, above which no ferromagnetism is observed. This temperature is called curie temperature.
