In high-pressure phenomena: Effects on electric and magnetic properties
…in a diamond-anvil cell using Mössbauer spectroscopy, which is a technique that can probe the coupling of a magnetic field with the nuclear magnetic dipole. High-pressure ferromagnetic-to-paramagnetic transitions were documented in iron metal and in magnetite (Fe₃O₄), while Curie temperatures (i.e., the temperature above which the ferromagnetic properties of a…

In Mössbauer effect: Apparatus
…this experiment is termed a Mössbauer effect Doppler-velocity spectrometer because it utilizes the Doppler shift to scan a region of energy in the vicinity of the energy of the gamma ray itself. A spectrometer utilizing this concept is shown schematically in Figure 1. A radioactive source is mounted on an…
