The discovery of a superconducting dome in the proximity of the magnetic to paramagnetic transition in the electronic phase diagram of MnP as a function of hydrostatic pressure has renewed the interest in the magnetic properties of this binary pnictide. Here we present an ab initio study obtained with Density Functional Theory (DFT) simulations as a function of pressure. We show that the itinerant-electron magnetism of MnP is well characterized by the mean-field Kohn-Sham method which correctly… Expand

TLDR
It is argued that this two-fluid behavior originates from the special crystal structure of MnP and may be relevant for understanding the pairing mechanism of the superconductivity at the border of the high pressure spiral phase. Expand
Orbital-dependent charge dynamics in MnP revealed by optical study
TLDR
The unpolarized/polarized optical conductivity study of high quality MnP single crystals at ambient pressure reveals two types of charge carriers with very different lifetimes, which may have an influence on the unconventional superconductivity and its interplay with helimagnetism at high pressures.

TLDR
The basic physical properties of these novel superconductors are reviewed and it is suggested that spin fluctuations may play crucial roles in mediating the Cooper pairing. Expand
