MnFe 2 O 4 polycrystalline powders were prepared by the chemical coprecipitation method. When the reaction temperature is above 80 ℃, through depositing and washing, the MnFe 2 O 4 can be obtained directly without calcining. However, when it is below 80 ℃, we have to calcine the precursor in order to obtain MnFe 2 O 4 , which does not result in pure spinal structure but a mixture of MnFe 2 O 4 and α-Fe 2 O 3 . The powders' magnetic property was characterized with a Vibrating Sample Magnetometer. The phase structure, crystal size and lattice constant were presented by an X-ray diffractometer. In addition, the morphology of the powder was observed with a scan electron microscope and a transmission electron microscope.

The influence of Goos–Hänchen shift on the total reflection of ultrashort light pulses is analyzed. If the incident pulse has an infinite beam width, the reflected pulse keeps the same shape as the incident pulse, but experiences a time delay. If the incident pulse has a spatially limited beam width (the pulsed beam), the reflected pulsed beam undergoes a carrier frequency shift and other distortions that depend on the Goos–Hänchen shift, the magnitude of the beam width, and the duration of the pulse.
