摘要：
The oscillation of tunnel splitting in Fee molecular clusters is obtained as a function of magnetic field applied along the hard axis by means of the instanton method with both effective potential field description of quantum spin system and the semiclassical treatment. The theoretical splittings of the instanton method are compared with the numerical result by diagonalization of the spin Hamilton operator and experimental observations.
