Phiên bản nam châm vĩnh cữu (HCS 1)
The HCS 1 stage is equipped with two magnetic circuits (Neodymium), assembled on a moveable sledge, which optionally can be automized. The system can be equipped with a low temperature as well as high temperature extension.
Phiên bản nam châm điện (HCS 10)
Optional to the permanent magnet, an electromagnet kit is available. The water cooled electromagnet is working in combination with a programmable power supply and a current reversal switch. The power supply can apply currents of up to 75 A, resulting in a variable magnetic fi eld strength of up to +/-1 T.
Tùy chọn nam châm Halbach (HCS 100)
The HCS 100 uses a magent in Halbach configuration (permanent magnet in donut configuration), in order to apply either a DC or an AC magnetic field to the sample. In combination with an AC current, provided by a Lock-in amplifier, this setup is a powerful tool for the investigation of challenging samples, as occuring offsets as well as noise can be suppressed in most cases.
