I would love to believe that SEMP discovered something no one has seen before, but let's be realistic. The core would have to be prepared in a previously unknown way. However, adding carbon is not a miracle mechanism because this method has been used for a long time. It's called carbonizing, right.
You are talking about slowing down the demagnetization process and demagnetizing it spontaneously.
That last sentence makes no sense, spontaneous is the opposite of slowing down. What SEMP claim is the forging process of carbonising (that usually uses rapid quenching by plunging into cold liquid) can use very slow quenching (cooling) like 10 hours, and this can give the iron a new characteristic that has not been used before. So it is different from the usual carbonizing.
Have you ever had a coil with a core and a load? What you call demagnetization is the BEMF force that acts every time for in and out.
You may call it BEMF but let's be clear, in this case it is an EMF (voltage) that comes from the flux changing wrt to time. The term BEMF is usually applied to electric motors, not transformers. It occurs on flux rise and on flux fall.
When the current from the coil is disconnected, the coil tends to get rid of the magnetic field, right.
You use the term “tends to” and I assume you mean that the current fall to zero is what creates the demagnetization. That is correct but it doesn't get rid of all the field and what remains is known as the remanent field Brem. Look at the BH loop for transformer steel and it is there at H=0.
If the transformer core maintains magnetism then it stops demagnetization because it cannot do so. The core is, for example, a magnet. You won't make the magnet act as a transformer core. This is why there is a problem here.
That Brem is not a problem in transformers because it gets wiped away each half cycle, but it does occur. And if you disconnect the coil at that Brem point it stays there. Science recognises that Brem as permanent magnetism and it is a problem in power transformers when they have undergone certain tests, see this thesis

The SEMP core would have to exhibit additional properties. E.g. magnetize with a small pulse up to 100% of its magnetic field. So, for example, a 1% pulse causes 100% core magnetization. Yes?
What do you mean by a 1% pulse? Do you mean pulse amplitude, if so 1% of what? SEMP use a small pulse
time but of amplitude to get your 100% magnetization. That is not a problem.
what about demagnetization? here we now have another problem. A load that is constant.
The demagnetization is not a problem, it occurs naturally on its own with no outside help. That is what SEMP have discovered with their long cooling time for the carbonizing process. And it happens fast enough for a significant voltage (your BEMF) to be induced into a coil and drive current through a load.
Disturbing things should be noticed, such as the removal of information from websites that informed about SEMP. Why ?
What information has been removed, can you be more specific.
