Nano Magneto Optical Kerr Effect (NanoMOKE)
The WEISTRON Nano Magneto Optical Kerr Effect (NanoMOKE) system is a powerful tool for measuring magnetic hysteresis loops of magnetic devices and magnetic materials. The WEISTRON Nano Magneto Optical Kerr Effect (NanoMOKE) system is also suitable for wafer-scale MOKE measurement.
System Description ( MOKE Model: MK1100 ):
1. Magnetic Field System
1-1. Electromagnet ( Magnetic field is higher than 1.2T as gap of iron cores is less than 10 mm )
1-2. Power Supply ( 750 Watts )
1-3. Embedded Gauss Meter ( Range : 30k Gauss to 1 Gauss )
2. Optical and Image System
2-1. Laser beam spot size is about 2 um and this allows hysteresis loops to be measured from small region.
2-2. Fully automated integrated optics: no laser beams or optics to align. Simply insert the sample, adjust the focus and start using the software.
3. Control System
3-1. Built-in computer systems (with Microsoft Windows)
3-2. Built-in Software Interface for Collecting and Analyzing Data
( Hysteresis loops can be measured automatically to find the initial curve, magnetization processes and coercivity of magnetic samples. Demagnetization process can be performed and measured automatically.)
3-3. Built-in Data Acquisition System
4-1. LCD Monitor
4-2. Keyboard and Mouse
