Magneto-Optical Kerr Microscope

Magneto-Optical Kerr Microscope

Highly flexible, advanced wide-field Kerr-microscope for magnetic domain research. Enhanced by image processing and equipped with electromagnets, domains and magnetization processes on all kinds of ferro- and ferrimagnetic materials can be studied at variable magnifications down to the resolution limit of optical microscopy. The microscope is based on the long experience of Prof. Jeffrey McCord and Prof. Rudolf Schäfer

Features:

High-end wide-field polarization microscope
Modified optics for optimal and homogeneous Kerr-contrast
Field of view from several millimeters down to micrometers using objective lenses from 5x to 100x (Oil immersion)
Rotatable electromagnet for in-plane fields up to 10 kOe (800 kA/m)
Optimized waveform generator for the generation of magnetic fields for general domain studies (ac, dc field, demagnetization etc.)
Real-time difference imaging technique for high contrast magnetic domain observation

High-Pressure-Milling-Vial

High-Pressure-Milling-Vial

High-Pressure-Milling-Vial by evico magnetis GmbH.

A new and powerful method for the synthesis of hydrogen storage materials and monitoring of hydrogenation reactions by reactive ball milling under high hydrogen atmosphere has been developed. It involves high-energy ball milling in an especially designed vial, allowing in-situ monitoring of temperature and, more importantly, of hydrogen pressure by incorporating a newly developed gas-temperature measurement system as well as a radio emitter into the vial lid. An external receiver transmits the data to a data acquisition computer.
