| Abstract: | The tunneling splitting in biaxial ferrimagnetic particles is obtained as a function of magnetic field applied along an arbitrary direction in the plane of hard and medium axes.We observe the oscillation of tunnel splitting with respect to the magnitude and the direction of the magnetic field due to the quantum phase interference of two tunneling paths of opposite windings.The oscillation is gradually smeared and in the end the tunnel splitting monotonously increases with the magnitude of the magnetic field when the direction of the magnetic field tends to the emedium axis.The behavior of the runnel splitting as a function of magnetic field is similar to the recent experimental observation with Fe 8 molecular clusters. |
