We regularly hear about magnets breaking the highest flux density records produced by laboratories, obviously the magnetization field intensity is generally not stated, so are there any materials that have low reluctance ( similar to silicon steel at 0.6-1T) at such high flux densities as most ferromagnetic materials would saturate well before this limit is reached ?

Important Note: From the first answer, it seems people are not aware of actual values, amorphous ferrite alloys, powder cores, silicon steel etc all saturate at a maximum of 1.6 T, other than Permendur(2.4 T) all magnetic materials currently in use saturate at 1.6 T or less. And I have googled this for quite some time to no result, that is why I asked in the first place.
