I was told M20 for frequencies around 10K by a mag engineer, but Stan's work is not the norm. I'm still not convinced that the core has to be thin and flat.

Tony reminded me that stan states M27 in one of his documents, I'll have to find out which document though to find out if it's for the  dual U core vic or another one.

ferrite with a perm around 2000 is good for 10khz.

The patent WO 89/12704 page 6 mentions the M27 core material,which is a steel laminate non grain.It is an alternate type of core for the flat core vic that we are talking about here.It's a Canadian patent.Figure 9 shows the coil layout.

Awesome, thanks for the info Don.

Now the hard part, finding a place to purchase some cores or core material.     Anyone have any info on where to get some?

So what were looking for is CRNGO M27 steel .105" thick?
