Pressure-induced high-spin low-spin transition in MnS2 and MnTe2
Pressure induced high-spin (HS) to low-spin (LS) transition in MnS2 was speculated by Chattopadhyay and von Schnering more than twenty years ago from their high pressure X-ray... -
Recrystallisation of LiCl-doped ice under pressure
In recent high pressure experiments (S. Klotz et al., Nature Materials, DOI 10.1038/ NMAT2422, 23.4.2009) we discovered a salt hydrate based on a high-pressure ice form, i.e.... -
