A Vacuum Evaporator for an Investigation of the Magneto-Optic Properties of Intermetallic Compound Films

摘要

This report describes an ultrahigh vacuum evaporator which is part of an apparatus for use in an investigation of the magneto-optical properties of ferromagnetic intermetallic compounds in thin film form. Samples can be prepared by vapor deposition from two sources and subsequent annealing in vacua of approximately 10 to the minus 9th power torr. A torque magnetometer built into the system can be used for magnetization measurements, and an external ellipsometer allows determination of magneto-optical constants on the films without removing them from the high vacuum in which they were prepared.
