Pressure Effects on the Hs-)LS Relaxation in (Zn1-xFex(6-Mepy)(3)Tren)(PF6)(2)
Laser flash photolysis experiments were performed on the mixed crystal [Zn1-xFex(6-mepy)(3)tren](PF6)(2) (x=0.00025) at 10 K in the pressure range between 1 bar and 20 kbar. An external pressure of 20 kbar accelerates the low-temperature tunneling process by almost. eight orders of magnitude.
