Description

The data is relative to an optical pump-THz emission measurement in KCoF3-Pt(5 nm) and KNiF3-Pt(5 nm) as a function of temperature and magnetic field.

tempKNiF3 and tempKCoF3 describe the temperature dependence of the THz emission measured at different fluences of the pump, in increasing order 0.026, 0.09, 0.28 mJ/cm3 (KCoF3) and 0.01, 0.09, 0.56 mJ/cm3 (KNiF3).

suscepKNiF3 and suscepKCoF3 are SQUID measuremenst of the susceptibility of KNiF3 and KCoF3 as a function of temperature.

polarizKNiF3 and polarizKCoF3 are time-traces of the emitted THz pulse measured when the sample is pumped by a linearly polarised pump along the [100], [010] and [001] plane.

DirectionKCoF contains time-traces of the emitted THz pulse when KCoF3-Pt is pumped from the Pt side or the substrate side with the same fluenece of 1.7 mJ/cm2.

Bdepend shows the amplitude of the THz emission in KCoF3 and KNiF3 as a function of magnetic field for the same pumping fluence of 1.7 mJ/cm2.
