Wave Function and Dynamic Equations to Calculate Spreading Energy of the Spin Waves in Ferromagnetic with Spin S=3/2

This reaserch aimed to :1-Finding energy of spin waves distribution in ferromagnetic material with spin S=3/2 starting from finding suitable wave function in chosed graphic kordinate and then the Hameltone and Lagrange and hence the dynamic equations which give concrate descripting of magnons energy levels and his spreading sped.
