Product Description

Cryogenic High-Magnetic-Field Laser Kerr Microimaging System

Product Introduction

Developed for the weak magnetism, small size, non-conductive nature, low coercive field, and low Curie temperature of two-dimensional ferromagnetic materials, this powerful characterization system features high magnetic detectionprecision, high-precision, micro-region spot measurement and positioning strong magnetic fields and wide temperature variation, meeting most of the magnetic characterization needs for two-di-mensional ferromagnetic materials.
