Abstract: A microscope device for observing a sample. The microscope device and the sample are located on an optical route. The microscope device includes an objective lens unit and an additional light source set. The light source set includes a circuit substrate, a battery and a light-emitting unit. The circuit substrate has a power source portion and a light source portion electrically connected to the power source portion. A connecting member and the battery are arranged at opposite sides of the power source portion. The light-emitting unit is arranged on the light source portion, and the distance between the light-emitting unit and the center axis of the optical route is greater than the radius of the objective lens unit. The battery activates the light-emitting unit to generate a light beam, and the light beam irradiates toward the center axis of the optical route.

Abstract: The invention relates to a process for forming a cobalt-iron alloy film. In particular, the process is performed under ultrasonic vibrations to form the cobalt-iron alloy film. The cobalt-iron alloy film consists of about 75-95 wt. % of cobalt, 4.5-20 wt. % of iron and 0.5-5 wt. % of phosphorus and also has peaks at about 43.2, 45.1, 50.4, 65.5, 74.1 and 83.2 2-theta degree (2?) in the X-ray diffraction pattern.
