Rare earth manganites (LaMnO3) exhibits colossal magnetoresistance

Efree members M. Baldini, V. V. Struzhkin, A. F. Goncharov, and W. L. Mao published the findings of their research on rare earth lanthanum manganite (LaMnO3), the parent compound for many hole doped manganites which exhibit colossal magnetoresistance (CMR).

Electromagnetic Probes

The highest Tc material has been found under high pressure; application of pressure also allows detailed studies of a multitude of physical probes in high-Tc superconductors at the borderline between the non-superconducting and superconducting states. Thus, in addition to chemical modification of materials, the pressure variable is one of the most important tools available to us for controlling materials processes at the level of electrons.

High-Pressure Transformations of Semiconductor Clathrates

Isostructural with hydrate systems are the semiconductor clathrates, which are based on a framework of semiconductor atoms, e.g. Ge and Si, arranged as a host lattice that trap, or enclathrate, metal atoms. Depending on the species and concentration of the guest, these materials show a wide range of functional properties, including semiconducting, metallic and even superconducting behavior.
