WebChapter 3. Microwave Theory and Background In conventional thermal demagnetisation heat is applied to a sample which creates lattice vibrations (phonons). These phonons are in a higher energy state than the surrounding magnetic system so they exchange energy with the magnetic system, and spin waves (magnons) are created (Walton et al., 1992; 1993). http://www.sciepub.com/reference/41765 Web1 de jan. de 2001 · The present analytical solution predicts the existence of thermal waves in a very thin film and presents the propagation process of thermal waves, the magnitude and shape of thermal waves, and the regularity of thermal wave decaying process in the films with different values of x 0 \τC.Such behavior cannot be predicted by the classical … chimney asbestos
