Thanks to a sample holder rod fitted with an optical fiber (A, B), we can irradiate samples in situ and measure the changes of the magnetization under or after the irradiation. Depending on the wavelength and the power used, irradiations can be carried out up to 5K. Photomagnetic measurements are possible in dc or ac mode.
