“…According to several recent experimental studies under highpressure, a high-pressure magnetic phase exists in Fe based alloys and compounds that show a low thermal expansion and large magneto-volume insanities, such as Fe-Ni Invar alloy [1][2][3], Fe-Pt Invar alloy [4][5][6][7][8], Fe-Ni-Mn Invar alloy [8], Y 2 Fe 17 [9,10].…”

“…XMCD benefits on the other hand from the x-ray brilliance and chemical selectivity just as IXS, while the polarization of the light provides the magnetic sensitivity. Following the seminal work of Odin et al (1998), a handful of XMCD experiments have been performed at the K-edges of transition metals under pressure up to the megabar range . We will refer to some of these results while discussing the spin state transitions of 3d metals.…”

Investigating electronic structure and excitations under extreme conditions gives access to a rich variety of phenomena. High pressure typically induces behavior such as magnetic collapse and the insulator-metal transition in 3d transition metals compounds, valence fluctuations or Kondo-like characteristics in f -electron systems, and coordination and bonding changes in molecular solids and glasses. This article reviews research concerning electronic excitations in materials under extreme conditions using inelastic x-ray scattering (IXS). IXS is a spectroscopic probe of choice for this study because of its chemical and orbital selectivity and the richness of information it provides. Being an all-photon technique, IXS has a penetration depth compatible with high pressure requirements. Electronic transitions under pressure in 3d transition metals compounds and f -electron systems, most of them strongly correlated, are reviewed. Implications for geophysics are mentioned. Since the incident X-ray energy can easily be tuned to absorption edges, resonant IXS, often employed, is discussed at length. Finally studies involving local structure changes and electronic transitions under pressure in materials containing light elements are briefly reviewed.

“…These studies pointed out the continuous transition among these states caused the Invar anomaly. On the other hand, some experimental studies reported the appearance of pressure-induced magnetic phase transition in Invar alloys [4][5][6][7]. Our group reported the appearances of highpressure magnetic phase and the disappearances of the ferromagnetic phase in Invar alloys, such as Fe 68.1 Ni 31.9 [8], Fe-Pt Invar alloys [9][10][11], Fe 65 Ni 27 Mn 8 [11] and Co 52.5-Fe 38 Cr 9.5 [12], using AC susceptibility (w 0 +iw 00 ) measurement technique.…”
