OK, assuming type 61, it is 0.1%/deg C.
IME, Type 78 is the usual choice for resonant antennas below 200 kHz (tempco of initial permeability = 1.0%/deg C). I have seen Type 33 used for broadband LF/MF antennas (tempco of initial permeability = 0.1%/deg C). Type 61 is generally not used below 200 kHz.
