A magneto-optical Kerr effect magnetometer for magnetic thin films, nanostructures, tunnel junctions and spintronic devices. A focused laser spot and video rate scanning laser microscope allow precise positioning on the sample and sensitive domain imaging.
The Model 648 is a 9 kW bipolar, 4-quadrant DC current source for large research electromagnets. It delivers up to +/-135 A at +/-75 V into a nominal 0.5 ohm, 0.5 H load, with 10 mA RMS current ripple. Protection covers short circuit, line faults and over temperature.
A Kerr effect magnetometer built around a large travel wafer stage, so hysteresis loops can be mapped across a whole wafer. Coercivity, remanence and exchange bias are extracted automatically from the measured loops.
