Abstract
An accurate measurement of the abrupt change of magnetic suscepti-bility in metals during melting and allotropic transformation was made. An attempt is also made to explain quantitatively these abrupt changes of susceptibility by applying the theory, which was proposed in the explanation of the change of susceptibility in metals caused by cold working.
As is well known, tin changes the sign of its magnetic susceptibility twice as the temperature rises, that is, at the transformation point and also at the melting point. These interesting phenomena have been satisfactorily explained by the above theory. A good agreement has also been found between the observed change of susceptibility during melting and its theoretical value in the case of copper, silver, gold, aluminium, mercury, sodium, potassium, rubidium and caesium.
