I have tried to understand the wiki article on Superparamagnetism...
https://en.wikipedia.org/wiki/Superparamagnetism
It seems to me that the level of Superparamagnetism can be adjusted in such
a way that a weak magnetic field can be applied to a ceramic magnet which
is highly superparamagnetic to reduce that superparamagnetism and therefore
the associated magnetic field of the magnet.
This technique is used to write and erase bits onto the surface of a
magnetic disk with a ceramic magnetic coating. The way this is done is to
adjust the number of magnetic domains that are impressed into each and
every nano particle that make up the structure of the ceramic magnet
surface through a specialized demagnetization process.
The way that the number of these magnetic domains are adjusted is done by
demagnetizing the magnet using a magnetic field that includes a specific
frequency. The magnetic domains within the nanoparticles become forever
sensitive to that frequency.
When this weak magnetic field is applied, the magnet becomes demagnetized
through random thermal vibration. When this alternating magnetic field is
removed, the magnetic field of the ceramic magnet returns.
This process is just what happens in the magnetic conditioning of the
billet, and the subsequent application of the weak activation magnetic
field.
This case is summarized by this snippet from the article
>From this frequency-dependent susceptibility, the time-dependence of the
magnetization for low-fields can be derived:
{\displaystyle \tau {\frac {\mathrm {d} M}{\mathrm {d} t}}+M=\tau \chi
_{b}{\frac {\mathrm {d} H}{\mathrm {d} t}}+\chi _{sp}H}[image: \tau {\frac
{{\mathrm {d}}M}{{\mathrm {d}}t}}+M=\tau \chi _{b}{\frac {{\mathrm
{d}}H}{{\mathrm {d}}t}}+\chi _{{sp}}H]
There is no time-dependence of the magnetization when the nanoparticles are
either completely blocked ({\displaystyle T\ll T_{B}}[image: T\ll T_{B}])
or completely superparamagnetic ({\displaystyle T\gg T_{B}}[image: T\gg
T_{B}]).
The condition we want to get to is when T = TB, that is when the
nanoparticles are right on the cutting edge between magnetism and
diamagnetism, so that a tiny magnetic field can turn them off or on.
I will add more detailed explanation if it looks like to you'll that there
is something to this adjustment in the superpara-magnification of the
ceramic billet to be sensitive to weak frequency-dependent magnetic fields.
Opinions are welcome.
