Small axial and transverse magnetic field systems for a57Fe M ssbauer study of Kramers systems
Autor: Jean-Louis Oddou, Olivier Horner, Christian Jeandey, Claudine Jeandey
Publikováno v: Measurement Science and Technology. 14:629-632
A small magnetic field, applied either parallel or perpendicular to the direction of Mossbauer γ-rays, is produced on an absorber by two Mossbauer sample-holders. The sample-holders constitute a convenient and affordable way to obtain the experiment
