Research - Grade MOKE Hysteresis Loop Tester
This research - grade MOKE system measures in - plane and out - of - plane hysteresis loops simultaneously, ideal for high - precision analysis of magnetic materials.
CONTACT US1. Product Overview
The Research-Grade MOKE Hysteresis Loop Tester enables high-precision magnetic characterization of:
- Ferromagnetic materials
- Artificial antiferromagnetic structures
- Two-dimensional materials
- Microelectronic devices
By applying both in-plane and vertical magnetic fields simultaneously, the system can measure hysteresis loops of any combination of field direction and magnetization component.
- Kerr rotation detection accuracy: up to 0.3 mdeg (RMS)
- Resolution: capable of detecting magnetization in a single atomic layer
- Sample holder: equipped with wire-tie design for electro-magneto-optical property characterization
The system is independently developed with high stability, strong scalability, and offers customization. Compared to similar instruments, it provides larger magnetic fields and higher precision while achieving in-plane and vertical loop measurements without altering the optical path.
In-plane magnetic field strength:
>1.0 T@8 mm air gap
>0.5 T@16 mm air gap
Vertical magnetic field strength:
>1.0 T@7 mm air gap
>0.5 T@16 mm air gap
2. Key Features
- Integrated gaussmeter sample holder with multiple ranges Maximum magnetic field resolution < 0.02 mT Collected field closely reflects the actual sample field
- Five-axis sample stage with laser real-time auto-alignment
- Four-pole vector magnet with dual in-plane and vertical field operation
- Highly focused laser beam spot for localized measurements
As small as 250 μm, users can obtain fine local magnetic information.
