Magnetic Field

The MLZ offers magnetic fields up to 12 Tesla. The different magnets may be used with additional sample environments, such as various inserts for low and high temperatures or even pressure cells. The table below gives all important information. If you have further questions, don’t hesitate to contact the sample environment group, responsible scientist or your local contact.
